2023-04-19util/e6400-flash-unlock: restore READMENicholas Chin
when nicholas added this, he removed the README because it's going on libreboot.org instead. however, i merged a WIP version of his page for now because i want to get the e6400 going in libreboot sooner. so, temp-readding this README. will just link to this on codeberg or something, from the lb docs NOTE: I didn't write this README, hence author field set in the commit. Nicholas wrote it, but I (Leah Rowe) am just adding it. so, git author set to nicholas, not me

2023-04-19Add E6400 flash unlock utilityNicholas Chin
Adding it to lbmk for now as it is not yet in coreboot. If it is merged into coreboot we can just reference the one there. The original README will be incorporated into a new page on lbwww, so README.md just points to a placeholder URL that should match the new page.
2023-04-19Add configs for the Latitude E6400Nicholas Chin
Tested the 4MiB ROMs but not the 8 or 16 MiB ones. This uses the same board.cfg as the GM45 ThinkPads with an IFD+GBE from ich9gen. Known issues: - The internal keyboard does not work properly in GRUB. It seems like the keyboard controller is outputing set 1 (XT) scancodes, but GRUB is interpreting them as set 2 (AT) scancodes. This may also have something to do with scancode translation. However, the keyboard works fine in SeaBIOS and Linux. USB keyboards also work properly. - The subsystem IDs in the GBE region are hardcoded for a Thinkpad in ich9gen, though this doesn't seem to cause issues in Linux. The vendor IFD and GBE region do have some differences from the generated binaries, though they do not appear to be critical.
2023-04-17gm45: re-add mitigations for no-microcode setupLeah Rowe
libreboot will still include microcode updates by default, but mitigations against broken speedstep and reboot (when microcode updates are excluded) were removed following the merge with osboot this patch restores those mitigations; the patch reverts coreboot to older smrr code (which works fine, it isn't critical to use the new behaviour) and disables peci (pointless feature) i'll probably re-tool this later to apply the changes conditionally to whether ucode is present this is not a change in policy. policy says: include cpu microcode updates by default policy also says: libreboot must be configurable microcode removal via cbfstool remove -n, counts as configuration, and in practise is not possible on gm45 patches in current libreboot; this patch corrects that problem, allowing the machines to work somewhat well (same stability issues as before, like MCE errors resulting in kernel panic on high CPU/memory usage, but i digress) happy... hacking
2023-04-15util/nvmutil: sort includes alphabeticallyLeah Rowe
small nitpick, but i try to use openbsd style since i like that style. upon further reading of their style guidelines today, it was revealed to me that for includes, they: * sort sys/ includes alphabetically, at the top * after sys/ includes, have an empty line * includes for networking-related headers below that * empty space below networking headers if there * after that, have the rest of the includes, sorted alphabetically at least, that is my understanding. i have to admit, it does look cleaner not really that critical but why not do it?

2023-04-14blobutil: support extracting ME from full ROMsLeah Rowe
In cases where the vendor update file contains a full ROM image encompassing IFD+GbE+ME+BIOS, blobutil was saving the *entire* ROM containing those, as me.bin. For example, if it's an 8MB ROM, blobutil would create a me.bin file that is actually the whole ROM containing: * Vendor IFD region * Vendor GbE(if it has one) * Vendor ME region * Vendor BIOS region This fix tries with -M and -O first. In this combination, me_cleaner shall extract me.bin (neutered) and save it. If that fails, then the normal method with just -O is tried, which by this logic would always be a lone ME image if it succeeds. I tested downloading ME images on existing boards with this, and it didn't break them, and this fixes the bug. This is done for HP 8200 SFF which Riku_V is adding to lbmk. I'm on IRC with Riku_V as I write this commit message! Super hot hotfix patch.

At the end of each line is an errant space. Fix that.

This fixes errors when running that script.
2023-04-09remove daisy and peach boards (todo: re-add)Leah Rowe
bl1 bootloader blobs needed, and lbmk doesn't currently auto-download these for insertion, so their presence in the build system is problematic because people might build these and think they work - they don't, due to the lack of those bl1 blobs notes about this are included in lbwww, on the compatibility list. these can be re-added and tested later, when lbmk handles those bl1 bootloader blobs
2023-04-09remove veyron boards temporarily (will re-add)Leah Rowe
u-boot is known broken on these, last revision known working is 2021.01 can bisect and find the fix. i'm putting this on the issue tracker (new one on codeberg)

the byteswap() function is used for big endian host compatibility, but it can also be used to swap words in the stored mac address

2023-04-06util/nvmutil: serious re-factoring (speed boost!)Leah Rowe
word/setWord no longer mitigates endianness. instead, all bytes are swapped after reading and before writing the file, and only if the host is big endian this improves performance on little endian hosts, which is most machines, and the code is much simpler, so it's more robust and less likely to break mac address endianness made more clear in code, including with a comment that explains it (the nvm section contains little endian words, *except* the mac address whose words are stored big endian)

2023-04-01blobutil/download: don't hardcode me.bin pathsLeah Rowe
Bruteforce it. Some executables are just using inno archival but some are simple LZMA. This patch handles both of them, and also the event where you have LZMA compressed files (even LZMA compressed files within LZMA compressed archives) within any inno/lzma compressed executable. It recursively scans inside a vendor update, to find a me.bin files for neutering with me_cleaner. This is in preparation for two new ports in Libreboot: * HP EliteBook 8560w * Apple MacBook Air 4,2 (2011) This script can literally be used with multiple vendors now. It is no longer specific just to Lenovo. I originally did this and other recent commits to the file, as one big commit, but I decided to split it all up into small commits.

2023-04-01blobutil/download: move main logic to the topLeah Rowe
Top-down order is easier to read, for greater understanding. What's moved is initialisation. The glue that calls Build_deps and Download_needed still need to be at the bottom.
