12 daysAdd auto-boot timeout for U-Boot's bootflow menuLeah Rowe
Otherwise, you have to press enter to boot your distro. With this, a timeout is created. After a number of seconds, which can be reconfigured, the first option selected will be booted, when generating a bootflow menu. The timeout is disabled when you navigate the menu; it only kicks in if you don't input anything on the keyboard. More information about how this works is in the U-Boot patches, within this patch. I've set the timeout to 8 seconds. Signed-off-by: Leah Rowe <leah@libreboot.org>
12 days8-sec auto-boot timeout for U-Boot's bootflow menuLeah Rowe
Otherwise, you have to press enter to boot, which is unacceptable for headless operation. Pressing anything other than enter an an option, such as the arrow keys, will disable the timeout. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-11-30u-boot: Enable USB with a preboot commandAlper Nebi Yasak
We need to initialize the USB subsystem before we can use USB devices like keyboards and external disks, by running `usb start`. Use the PREBOOT config option to run the necessary command before U-Boot tries to automatically boot anything. It's already enabled for boards other than gru_kevin and gru_bob, so just update those two configs. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2024-11-30u-boot: Update ARM64 boards to v2024.10Alper Nebi Yasak
Set default U-Boot revision to v2024.10 and rebase patches on top of that. The video subsystem now has switched to using the 'cyclic' mechanism, so the code around one of the video patches changed a bit. x86 boards were already switched to v2024.10. Update U-Boot for the remaining ARM64 boards as usual: - Turn old configs into defconfigs (./update trees -s u-boot) - Save the diff from old upstream defconfig (diffconfig $theirs $ours) - Update U-Boot revision, rebase patches, and clean old trees - Prepare new U-Boot tree (./update trees -f u-boot) - Review the diffconfigs to see if any options were renamed upstream - Copy over the new upstream defconfigs and apply earlier diff - Turn new defconfigs into configs (./update trees -l u-boot) Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2024-11-20U-Boot x86: Avoid clearing the VESA displayLeah Rowe
This is a patch from Simon Glass. U-Boot clears the display when it starts up, but was asking the VESA driver to do the same, needlessly; this patch avoids the latter. A further patch is also included, which provides a better message when jumping into long mode on the SPL (64-bit) target, dumping it on the serial console instead of using printf.

2024-11-19u-boot x86 serial/ns16550: disable UART as neededLeah Rowe
U-Boot was hanging on hardware, but not Qemu. This is because on the machines tested, namely the X200 and E6230 laptops supported in Libreboot, the UART was disabled from coreboot. This U-Boot patch from Simon Glass works around the issue by silently disabling the UART when it isn't there. Instead, output is sent to the display and U-Boot no longer hangs.

2024-11-19Update x86 U-Boot to v2024.10 (was v2024.07)Leah Rowe
It's a new experimental payload in Libreboot, so we may aswell start with the very latest release of U-Boot. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-11-19Add U-Boot x86_64 payloadLeah Rowe
Currently seems to stall when booted from the GRUB payload, but works when booted from the SeaBIOS menu. I also tested it as a standalone payload and it seems to boot. Will test on hardware next, and start adding it to more mainboards. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-11-03Experimental U-Boot payload (32-bit dtb, U-Boot)Leah Rowe
NOTE: Support added for xarch target x86_64-elf, but U-Boot failed to build with this error: OBJCOPY lib/efi_loader/helloworld.efi x86_64-elf-objcopy: lib/efi_loader/helloworld_efi.so: invalid bfd target make[2]: *** [scripts/Makefile.lib:476: lib/efi_loader/helloworld.efi] Error 1 Since I'm building U-Boot for x86_64 *on* an x86-64 host, and since that is currently the recommended type of machine to use for lbmk development, and since the other x86 payloads currently don't cross compile anyway, this is an acceptable compromise for now. This is because at present, I'm not making U-Boot the primary payload on x86, instead preferring to chain it from GRUB and SeaBIOS. The target.cfg file for x86 u-boot shows xarch/xtree commented. Uncomment these to compile on crossgcc instead of hostcc. I mention 64-bit because I initially did this first, but decided to do 32-bit first. I'll work on the 64-bit one next (SPL). It's only enabled in QEMU for now. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-07-11u-boot: Fix display initialization on gru boardsAlper Nebi Yasak
U-Boot has migrated to using upstream device-tree files for gru boards, but the clock driver doesn't yet support setting rates for a certain clock that upstream uses for the eDP display. It happens to work without it, so for now remove the clock setting until the driver is fixed. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2024-07-11u-boot: Avoid breaking build for U-Boot-only binman imagesAlper Nebi Yasak
Commit 46e01c0e1dad ("u-boot: Avoid building U-Boot-only binman images") added a patch that prevents an error while building U-Boot, due to some U-Boot images needing a copy of BL31 that we are not passing in. Removing build instructions for these images isn't really necessary, when we can instead tell the build tool that it shouldn't exit with an error. It checks a BINMAN_ALLOW_MISSING environment variable for this, but just unconditionally replace the check with the argument. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2024-07-11u-boot: Update to v2024.07Alper Nebi Yasak
Set default U-Boot revision to v2024.07 and rebase patches on top of that. One patch that fixes drawing box characters (UTF-8 to CP437) had an alternative merged, another hack we have to fix regulator issues is no longer neccessary as the issue is fixed, and my QEMU patches were merged upstream, so drop these patches. One patch we have to disable binman images can be replaced by a simpler alternative so drop it too. Upstream kconfig status is still unstable, so updating configs with `make oldconfig` would miss important upstream changes, since they rely on carrying defaults via upstream defconfigs. Update the configs as such, like before: - Turn old configs into defconfigs (./update trees -s u-boot) - Save the diff from old upstream defconfig (diffconfig $theirs $ours) - Update U-Boot revision, rebase patches, and clean old trees - Prepare new U-Boot tree (./update trees -f u-boot) - Review the diffconfigs to see if any options were renamed upstream - Copy over the new upstream defconfigs and apply earlier diff - Turn new defconfigs into configs (./update trees -l u-boot) Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2024-06-06handle build.list from config/data/, not config/Leah Rowe
certain code checks for build.list, to skip it, for example in items() we already use config/data/grub to store grub config data that applied to all trees create these directories too: config/data/coreboot config/data/u-boot config/data/seabios move the respective build.list files in here, and also to config/data/grub now multi-tree projects contain, per directory, just the target.cfg file and the patches directory. this is much cleaner, because some of the logic can be simplified more Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-01u-boot on qemu: remove currently unused x86 targetLeah Rowe
it doesn't build, at present, but isn't used by any coreboot targets, so the build issue does not come up during release builds, but i did find it laying around during my audits. x86 qemu is on todo for libreboot, on all x86 boards, but the current config is broken, so: remove it. it's very much a requirement that anything in lbmk should work.

2023-12-27update/trees: further simplify crossgcc handlingLeah Rowe
arch no longer needs to be set, on multi-tree projects, and it has been renamed to xarch the new behaviour is: if xarch is set, treat it as a list of crossgcc targets and go through the list. set the first one as the target, for what lbmk builds, but build all of the defined crossgccc targets crossgcc_ada is now xlang, and defines which languages to build, rather than whether to build gcc-gnat Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-21update/trees: simplified crossgcc handlingLeah Rowe
only call crossgcc for coreboot and u-boot, but use hostcc for everything else. simplify the checking of which architecture to compile for. "arch" in target.cfg files has been modified, to allow further simplification. without this patch, the logic currently only *barely* avoids using crossgcc on things like utils, and only works in practise because, in practise, lbmk only works on x86_64 anyway. the new logic, as per this patch, is simpler and more robust.

2023-10-14u-boot: gru: Do not persist EFI variablesAlper Nebi Yasak
By default U-Boot stores EFI variables in a ubootefi.var file in whatever EFI System Partition it finds, which would be a FAT filesystem. I'm occasionally finding out while testing that my ESPs somehow end up with a corrupted filesystem, and I'm suspecting it's this. For now, disable storing EFI environment variables on disk so that U-Boot doesn't try to manipulate the filesystem. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2023-10-14u-boot: gru: Enable more EFI commandsAlper Nebi Yasak
Enable U-Boot commands to manipulate EFI environment storage, to self-test EFI implementation, and to run a basic EFI test application. These are so that we can test and debug EFI functionality easier. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2023-10-14u-boot: gru: Enable more bootstd featuresAlper Nebi Yasak

2023-10-14u-boot: gru: Do not reset on panicAlper Nebi Yasak
Normally U-Boot immediately resets the board on a panic. I had run into "Synchronous Abort"s from shim and rEFInd, and having a traceback in those cases can be useful. Hang instead of resetting, so the panic reason stays on the screen. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

2023-10-14u-boot: gru: Disable VIDEO_COPYAlper Nebi Yasak
U-Boot can keep a "copy" framebuffer to read from, for devices where reading from hardware framebuffer is expensive. This needs the video driver to support it. The Rockchip video driver doesn't need or support it, so this option does nothing on gru boards. Disable it. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2023-10-14u-boot: Set EFI variable buffer size to upstream valueAlper Nebi Yasak
U-Boot upstream used to have 16KB for EFI variables, and this was causing problems with shim. Commit f0236acbc663 ("u-boot: Increase EFI variable buffer size") fixed this by raising it to 32KB in our builds. It has now been raised to 64K upstream, so raise it here as well.

2023-10-14u-boot: Avoid building U-Boot-only binman imagesAlper Nebi Yasak
For Rockchip boards U-Boot tries to build SPI and MMC images that require an externally built BL31 file to be provided, and the build fails otherwise. This is not really as configurable as it should be. In Libreboot, we only care about the build outputs for U-Boot proper. There is a BL31 built during our coreboot builds, but using that in U-Boot builds is a chicken-and-egg problem. Building BL31 outside the coreboot build and passing it to both projects is possible, but needs work. For now, stop trying to build these U-Boot-only images as a workaround, by removing the binman image descriptions from the device-tree sources. Additionally, disable in our configs the BINMAN_FDT functionality that allows using these at runtime as it requires them to be present. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

Set default U-Boot revision to v2023.01 and rebase patches on top of that. Another series about 16x32 fonts was merged upstream, so drop some now-unnecessary patches we had for that. For the video damage tracking series, switch to the version I'm trying to upstream. Upstream kconfig status is a bit unstable, so updating configs with `make oldconfig` would miss important upstream changes, since they rely on carrying defaults via upstream defconfigs.

2023-10-14build/fw/coreboot: Fix misuse of raw u-boot.bin as payloadAlper Nebi Yasak
The "u-boot.bin" file generated by U-Boot builds is a raw binary. When adding payloads to a CBFS, we need to use ELF files with add-payload or manually pass the entry point and load address of the payload binary with add-flat-binary. We primarily use the "u-boot.elf" which gets build with the REMAKE_ELF option, as it also has the necessary device-tree binary that U-Boot usually needs to work. When the option is not set (e.g. for QEMU), we need to use the "u-boot" file which is an ELF. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
