+# Porting coreboot using autoport
+
+## Supported platforms
+
+### Chipset
+For any Sandy Bridge or Ivy Bridge platform the generated result should
+be bootable, possibly with minor fixes.
+
+### EC / SuperIO
+EC support is likely to work on Intel-based thinkpads. Other laptops are
+likely to miss EC support. SuperIO support on desktops is more likely to
+work out of the box than any EC.
+
+## How to use autoport
+
+Enable as many devices as possible in the firmware setup of your system.
+This is useful to detect as many devices as possible and make the port
+more complete, as disabled devices cannot be detected.
+
+Boot into target machine under any Linux-based distribution and install
+the following tools on it:
+* `gcc`
+* `golang`
+* `lspci`
+* `dmidecode`
+* `acpidump` (part of `acpica` on some distros)
+
+Clone the coreboot tree and `cd` into it. For more detailed steps, refer
+to Rookie Guide, Lesson 1. Afterwards, run these commands:
+
+ cd util/ectool
+ make
+ cd ../inteltool
+ make
+ cd ../superiotool
+ make
+ cd ../autoport
+ go build
+ sudo ./autoport --input_log=logs --make_logs --coreboot_dir=../..
+
+ Note: in case you have problems getting gcc and golang on the target
+ machine, you can compile the utilities on another computer and copy
+ the binaries to the target machine. You will still need the other
+ listed programs on the target machine, but you may place them in the
+ same directory as autoport.
+
+Check for unknown detected PCI devices, e.g.:
+
+ Unknown PCI device 8086:0085, assuming removable
+
+If autoport says `assuming removable`, you are fine. If it doesn't,
+you may want to add the relevant PCI IDs to autoport. Run `lspci -nn`
+and check which device this is using the PCI ID. Devices which are not
+part of the chipset, such as GPUs or network cards, can be considered
+removable, whereas devices inside the CPU or the PCH such as integrated
+GPUs and bus controllers (SATA, USB, LPC, SMBus...) are non-removable.
+
+Your board has now been added to the tree. However, do not flash it
+in its current state. It can brick your machine. Instead, keep this
+new port and the logs from `util/autoport/logs` somewhere safe. The
+following steps will back up your current firmware, which is always
+recommended, since coreboot may not boot on the first try.
+
+Disassemble your computer and find the flash chip(s). Since there could be
+more than one, this guide will refer to "flash chips" as one or more chips.
+Refer to <https://flashrom.org/Technology> as a reference. The flash chip is
+usually in a `SOIC-8` (2x4 pins, 200mil) or `SOIC-16` (2x8 pins) package. As
+it can be seen on flashrom's wiki, the former package is like any other 8-pin
+chip on the mainboard, but it is slightly larger. The latter package is much
+easier to locate. Always make sure it is a flash chip by looking up what its
+model, printed on it, refers to.
+
+There may be a smaller flash chip for the EC on some laptops, and other chips
+such as network cards may use similar flash chips. These should be left as-is.
+If in doubt, ask!
+
+Once located, use an external flasher to read the flash chips with `flashrom -r`.
+Verify with `flashrom -v` several times that reading is consistent. If it is not,
+troubleshoot your flashing setup. Save the results somewhere safe, preferably on
+media that cannot be easily overwritten and on several devices. You may need this
+later. The write process erases the flash chips first, and erased data on a flash
+chip is lost for a very long time, usually forever!
+
+Compile coreboot for your ported mainboard with some console enabled. The most
+common ones are EHCI debug, serial port and SPI flash console as a last resort.
+If your system is a laptop and has a dedicated video card, you may need to add
+a video BIOS (VBIOS) to coreboot to be able to see any video output. Desktop
+video cards, as well as some MXM video cards, have this VBIOS on a flash chip
+on the card's PCB, so this step is not necessary for them.
+
+Flash coreboot on the machine. On recent Intel chipsets, the flash space is split
+in several regions. Only the one known as "BIOS region" should be flashed. If
+there is only one flash chip present, this is best done by adding the `--ifd`
+and `-i bios` parameters flashrom has (from v1.0 onwards) to specify what flash
+descriptor region it should operate on. If the ME (Management Engine) region is
+not readable, which is the case on most systems, use the `--noverify-all`
+parameter as well.
+
+For systems with two flash chips, this is not so easy. It is probably better to
+ask in coreboot or flashrom communication channels, such as via IRC or on the
+mailing lists.
+
+Once flashed, try to boot. Anything is possible. If a log is generated, save it
+and use it to address any issues. See the next section for useful information.
+Find all the sections marked with `FIXME` and correct them.
+
+Send your work to review.coreboot.org. I mean it, your effort is very appreciated.
+Refer to Rookie Guide, Lesson 2 for instructions on how to submit a patch.
+
+## Manual fixes
+### SPD
+In order to initialize the RAM memory, coreboot needs to know its timings, which vary between
+modules. Socketed RAM has a small EEPROM chip, which is accessible via SMBus and contains the
+timing data. This data is usually known as SPD. Unfortunately, the SMBus addresses may not
+correlate with the RAM slots and cannot always be detected automatically. The address map is
+encoded in function `mainboard_get_spd` in `romstage.c`. By default, autoport uses the most
+common map `0x50, 0x51, 0x52, 0x53` on everything except for Lenovo systems, which are known
+to use `0x50, 0x52, 0x51, 0x53`. To detect the correct memory map, the easiest way is to boot
+on the vendor firmware with just one module in channel 0, slot 0, and check the SMBus address
+the EEPROM has. Under Linux, you can use these commands to see what is on SMBus:
+
+ $ sudo modprobe i2c-dev
+ $ sudo modprobe i2c-i801
+ $ sudo i2cdetect -l
+ i2c-0 i2c i915 gmbus ssc I2C adapter
+ i2c-1 i2c i915 gmbus vga I2C adapter
+ i2c-2 i2c i915 gmbus panel I2C adapter
+ i2c-3 i2c i915 gmbus dpc I2C adapter
+ i2c-4 i2c i915 gmbus dpb I2C adapter
+ i2c-5 i2c i915 gmbus dpd I2C adapter
+ i2c-6 i2c DPDDC-B I2C adapter
+ i2c-7 i2c DPDDC-C I2C adapter
+ i2c-8 i2c DPDDC-D I2C adapter
+ i2c-9 smbus SMBus I801 adapter at 0400 SMBus adapter
+
+ $ sudo i2cdetect 9
+ WARNING! This program can confuse your I2C bus, cause data loss and worse!
+ I will probe file /dev/i2c-9.
+ I will probe address range 0x03-0x77.
+ Continue? [Y/n] y
+ 0 1 2 3 4 5 6 7 8 9 a b c d e f
+ 00: -- -- -- -- -- 08 -- -- -- -- -- -- --
+ 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+ 20: -- -- -- -- 24 -- -- -- -- -- -- -- -- -- -- --
+ 30: 30 31 -- -- -- -- -- -- -- -- -- -- -- -- -- --
+ 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

+ 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
+ 70: -- -- -- -- -- -- -- --
+
+Make sure to replace the `9` on the last command with the bus number for SMBus on
+your system. Here, there is a module at address `0x50`. Since only one module was
+installed on the first slot of the first channel, we know the first position of
+the SPD array must be `0x50`. After testing all the slots, your `mainboard_get_spd`
+should look similar to this:
+
+ void mainboard_get_spd(spd_raw_data *spd) {
+ read_spd(&spd[0], 0x50);
+ read_spd(&spd[1], 0x51);
+ read_spd(&spd[2], 0x52);
+ read_spd(&spd[3], 0x53);
+ }
+
+Note that there should be one line per memory slot on the mainboard.
+
+Note: slot labelling may be missing or unreliable. Use `inteltool` to see
+which slots have modules in them.
+
+This procedure is ideal, if your RAM is socketed. If you have soldered RAM,
+remove any socketed memory modules and check if any EEPROM appears on SMBus.
+If this is the case, you can proceed as if the RAM was socketed. However,
+you may have to guess some entries if there multiple EEPROMs appear.
+
+Most of the time, soldered RAM does not have an EEPROM. Instead, the SPD data is
+inside the main flash chip where the firmware is. If this is the case, you need
+to generate the SPD data to use with coreboot. Look at `inteltool.log`. There
+should be something like this:
+
+ /* SPD matching current mode: */
+ /* CH0S0 */

+ EOF (press Ctrl + D)
+
+Then, move the generated file into your mainboard's directory
+and hook it up to the build system by adding the following
+lines to `Makefile.mk`:
+
+ cbfs-files-y += spd.bin
+ spd.bin-file := spd.bin
+ spd.bin-type := raw
+
+Now we need coreboot to use this SPD file. The following example
+shows a hybrid configuration, in which one module is soldered and
+the other one is socketed:
+
+ void mainboard_get_spd(spd_raw_data *spd)
+ {
+ void *spd_file;
+ size_t spd_file_len = 0;
+ /* C0S0 is a soldered RAM with no real SPD. Use stored SPD. */
+ spd_file = cbfs_boot_map_with_leak("spd.bin", CBFS_TYPE_RAW,
+ &spd_file_len);
+ if (spd_file && spd_file_len >= 128)
+ memcpy(&spd[0], spd_file, 128);
+
+ /* C1S0 is a physical slot. */
+ read_spd(&spd[2], 0x52);
+ }
+
+If several slots are soldered there are two ways to handle them:
+
+* If all use the same SPD data, use the same file for all the slots. Do
+ not forget to copy the data on all the array elements that need it.
+* If they use different data, use several files.
+
+If memory initialization is not working, in particular write training (timB)
+on DIMM's second rank fails, try enabling rank 1 mirroring, which can't be
+detected by inteltool. It is described by SPD field "Address Mapping from Edge
+Connector to DRAM", byte `63` (`0x3f`). Bit 0 describes Rank 1 Mapping,
+0 = standard, 1 = mirrored; set it to 1. Bits 1-7 are reserved.
+
+### `board_info.txt`
+
+`board_info.txt` is a text file used in the board status page to list all
+the supported boards and their specifications. Most of the information
+cannot be detected by autoport. Common entries are:
+
+* `ROM package`, `ROM protocol` and `ROM socketed`:
+ These refer to the flash chips you found earlier. You can visit
+ <https://flashrom.org/Technology> for more information.
+
+* `Release year`: Use the power of Internet to find that information.
+* `Category`: This describes the type of mainboard you have.
+ Valid categories are:
+ * `desktop`. Desktops and workstations.
+ * `server`. Servers.
+ * `laptop`. Laptops, notebooks and netbooks.
+ * `half`. Embedded / PC/104 / Half-size boards.
+ * `mini`. Mini-ITX / Micro-ITX / Nano-ITX
+ * `settop`. Set-top-boxes / Thin clients.
+ * `eval`. Development / Evaluation Boards.
+ * `sbc`. Single-Board computer.
+ * `emulation`: Virtual machines and emulators. May require especial care
+ as they often behave differently from real counterparts.
+ * `misc`. Anything not fitting the categories above. Not recommended.
+
+* `Flashrom support`: This means whether the internal programmer is usable.
+ If flashing coreboot internally works, this should be set to `y`. Else,
+ feel free to investigate why it is not working.
+
+### `USBDEBUG_HCD_INDEX`
+
+Which controller the most easily accessible USB debug port is. On Intel,
+1 is for `00:1d.0` and 2 is for `00:1a.0` (yes, it's reversed). Refer to
+<https://www.coreboot.org/EHCI_Debug_Port> for more info.
+
+If you are able to use EHCI debug without setting the HCD index manually,
+this is correct.
+
+### `BOARD_ROMSIZE_KB_2048`
+
+This parameter refers to the total size of the flash chips coreboot will be in.
+This value must be correct for S3 resume to work properly. This parameter also
+defines the size of the generated coreboot image, but that is not a major issue
+since tools like `dd` can be used to cut fragments of a coreboot image to flash
+on smaller chips.
+
+This should be detected automatically, but it may not be detected properly in
+some cases. If it was not detected, put the correct total size here to serve
+as a sane default when configuring coreboot.
+
+### `DRAM_RESET_GATE_GPIO`
+
+When the computer is suspended to RAM (ACPI S3), the RAM reset signal must not
+reach the RAM modules. Otherwise, the computer will not resume and any opened
+programs will be lost. This is done by powering down a MOSFET, which disconnects
+the reset signal from the RAM modules. Most manufacturers put this gate on GPIO
+60 but Lenovo is known to put it on GPIO 10. If suspending and resuming works,
+this value is correct. This can also be determined from the board's schematics.
+
+## GNVS
+
+`mainboard_fill_gnvs` sets values in GNVS, which then ACPI makes use of for
+various power-related functions. Normally, there is no need to modify it
+on laptops (desktops have no "lid"!) but it makes sense to proofread it.
+
+## `gfx.ndid` and `gfx.did`
+
+Those describe which video outputs are declared in ACPI tables.
+Normally, there is no need to have these values, but if you miss some
+non-standard video output, you can declare it there. Bit 31 is set to
+indicate the presence of the output. Byte 1 is the type and byte 0 is
+used for disambigution so that ID composed of byte 1 and 0 is unique.
+
+Types are:
+* 1 = VGA
+* 2 = TV
+* 3 = DVI
+* 4 = LCD
+
+## `c*_acpower` and `c*_battery`
+
+Which mwait states to match to which ACPI levels. Normally, there is no
+need to modify anything unless your device has very special power saving
+requirements.
+
+## `install_intel_vga_int15_handler`
+
+This is used with the Intel VGA BIOS, which is not the default option.
+It is more error-prone than open-source graphics initialization, so do
+not bother with this until your mainboard boots. This is a function
+which takes four parameters:
+1. Which type of LCD panel is connected.
+2. Panel fit.
+3. Boot display.
+4. Display type.
+
+Refer to `src/drivers/intel/gma/int15.h` to see which values can be used.
+For desktops, there is no LCD panel directly connected to the Intel GPU,
+so the first parameter should be `GMA_INT15_ACTIVE_LFP_NONE`. On other
+mainboards, it depends.
+
+## CMOS options
+
+Due to the poor state of CMOS support in coreboot, autoport does not
+support it and this probably won't change until the format in the tree
+improves. If you really care about CMOS options:
+
+* Create files `cmos.layout` and `cmos.default`
+* Enable `HAVE_OPTION_TABLE` and `HAVE_CMOS_DEFAULT` in `Kconfig`
+
+## EC (lenovo)
+
+You need to set `has_keyboard_backlight` (backlit keyboard like X230),
+`has_power_management_beeps` (optional beeps when e.g. plugging the cord
+in) and `has_uwb` (third MiniPCIe slot) in accordance to functions available
+on your machine
+
+In rare cases autoport is unable to detect GPE. You can detect it from
+dmesg or ACPI tables. Look for line in dmesg like
+
+ ACPI: EC: GPE = 0x11, I/O: command/status = 0x66, data = 0x62
+
+This means that GPE is `0x11` in ACPI notation. This is the correct
+value for `THINKPAD_EC_GPE`. To get the correct value for `GPE_EC_SCI`
+you need to substract `0x10`, so value for it is `1`.
+
+The pin used to wake the machine from EC is guessed. If your machine doesn't
+wake on lid open and pressing of Fn, change `GPE_EC_WAKE`.
+
+Keep `GPE_EC_WAKE` and `GPE_EC_SCI` in sync with `gpi*_routing`.
+`gpi*_routing` matching `GPE_EC_WAKE` or `GPE_EC_SCI` is set to `2`
+and all others are absent.
+
+If your dock has LPC wires or needs some special treatement you may
+need to add codes to initialize the dock and support code to
+DSDT. See the `init_dock()` for `x60`, `x200` or `x201`.
+
+## EC (generic laptop)
+
+Almost any laptop has an embedded controller. In a nutshell, it's a
+small, low-powered computer designed to be used on laptops. Exact
+functionality differs between machines. Its main functions include:
+
+* Control of power and rfkill to different component
+* Keyboard (PS/2) interface implementation
+* Battery, AC, LID and thermal information exporting
+* Hotkey support
+
+autoport automatically attempts to restore the dumped config but it
+may or may not work and may even lead to a hang or powerdown. If your
+machine stops at `Replaying EC dump ...` try commenting EC replay out
+
+autoport tries to detect if machine has PS/2 interface and if so calls
+`pc_keyboard_init` and exports relevant ACPI objects. If detection fails
+you may have to add them yourself
+
+ACPI methods `_PTS` (prepare to sleep) and `_WAK` (wake) are executed
+when transitioning to sleep or wake state respectively. You may need to
+add power-related calls there to either shutdown some components or to
+add a workaround to stop giving OS thermal info until next refresh.
+
+For exporting the battery/AC/LID/hotkey/thermal info you need to write
+`acpi/ec.asl`. For an easy example look into `apple/macbook21` or
+`packardbell/ms2290`. For information about needed methods consult
+relevant ACPI specs. Tracing which EC events can be done using
+[dynamic debug](https://wiki.ubuntu.com/Kernel/Reference/ACPITricksAndTips)
+
+EC GPE needs to be routed to SCI in order for OS in order to receive
+EC events like "hotkey X pressed" or "AC plugged". autoport attempts
+to detect GPE but in rare cases may fail. You can detect it from
+dmesg or ACPI tables. Look for line in dmesg like
+
+ ACPI: EC: GPE = 0x11, I/O: command/status = 0x66, data = 0x62
+
+This means that GPE is `0x11` in ACPI notation. This is the correct
+value for `_GPE`.
+
+Keep GPE in sync with `gpi*_routing`.
+`gpi*_routing` matching `GPE - 0x10` is set to `2`
+and all others are absent. If EC has separate wake pin
+then this GPE needs to be routed as well
