Saved SeaBIOS configuration options for mainboards.
by Martin Roth 30 Nov '15

30 Nov '15

I recently posted a patch that would allow the coreboot build to use a saved SeaBIOS .config file stored in the mainboard directory. The initial reason for this was to replace one existing SeaBIOS configuration option that was in coreboot's Kconfig, and to remove the need for a second option that was about to be added. The intention behind this is not to add full config files, but to add individual options that are required for the platforms. That said, saving a full config will almost certainly happen at some point since this change doesn't prevent this. I'm not sure how big an issue this really is, other than creating some maintenance problems. Another side effect of this is that a user could point to a saved .config outside of the coreboot tree, to customize the SeaBIOS. I don't think this should present a problem, as the .config file for SeaBIOS is getting saved in CBFS. If we want to minimize this, the prompt in Kconfig can be removed, preventing the option from showing up in menuconfig (or your favorite config method). It was requested that I post this change to the mailing list for thoughts and review. The patches in question are here: payloads/external/SeaBIOS: Add option for saved SeaBIOS .config https://review.coreboot.org/#/c/12568 intel/mohonpeak: Change SEABIOS_MALLOC_UPPERMEMORY to config_seabios https://review.coreboot.org/#/c/12569 SeaBIOS/Kconfig: Remove SEABIOS_MALLOC_UPPERMEMORY option https://review.coreboot.org/#/c/12570 payloads/Seabios: add SEABIOS_NO_HARDWARE_IRQ symbol https://review.coreboot.org/#/c/12534/ Thoughts? Review? Downsides I didn't think of? Martin

What is mrc.bin and system agent binary?
by Iru Cai 29 Nov '15

29 Nov '15

Hi, I've bought a Chromebook Pixel 2013 and want to reflash the firmware. I saw in the config that I need a system agent binary. I looked into 3rdparty/blobs/nb/intel/sb/ and found three binary files, and the default one in nb/intel/sb/kconfig is systemagent-r6.bin. And I read the google/link wiki and saw another word called mrc.bin. Are they the same thing? And can I use the coreboot native MRC code for google/link? Regards, Iru

[ANNOUNCE] SeaBIOS 1.9.0
by Kevin O'Connor 28 Nov '15

28 Nov '15

The 1.9.0 version of SeaBIOS has now been released. For more information on the release, please see: http://seabios.org/Releases New in this release: * The default boot menu key is now the ESC key (instead of F12) * Initial support for Trusted Platform Module (TPM) hardware and BIOS calls * Initial support for chain loading SeaBIOS from Grub (via multiboot support) * Initial support for booting from SD cards on real hardware * virtio 1.0 device support * The build will no longer include the build hostname or build time on "clean" builds. This makes the build binaries more "reproducible". * Basic support for running SeaBIOS on Baytrail Chromebooks * SeaVGABIOS improvements: * Improved support for old versions of x86emu (the "leal" instruction is now emulated) * Several bug fixes and code cleanups For information on obtaining SeaBIOS, please see: http://seabios.org/Download ===== git shortlog -n rel-1.8.0..rel-1.9.0 ===== Kevin O'Connor (126): docs: add page for SeaVGABIOS docs: Add page describing the patch contribution process docs: Add page on available CBFS/fw_cfg runtime config files docs: Prefer triple backticks to multiple lines with single backticks smp: Fix smp race introduced in 0673b787 docs: Note release date of 1.8.1 vgabios: On bda_save_restore() the saved vbe_mode also has flags in it vgabios: Don't use extra stack if it appears a modern OS is in use docs: Clarify that pci-optionrom-exec doesn't apply to roms in cbfs checkstack: Replace function information tuple with class checkstack: Simplify yield calculations checkstack: Prefer passing "function" class instead of function address smbios: Use integer signature instead of string signature vgabios: Don't use "smsww" instruction -

ThinkPad X120e/X140e
by Łukasz Dobrowolski 27 Nov '15

27 Nov '15

Hi all! I would like to port coreboot to one of my laptops (ThinkPad X140e and X120e). Both of them have AMD APU-s. I would be grateful if somebody could take a look at attachments and tell me how challenging the task appears to be. I read and searched for information about those for few days now. What I found (apart from attachments): X120e: Logical mainboard schematics I'm 90% sure I can get my hands on physical mainboard schematics if needed. I have detailed pictures of the mainboard. X140e: I can make detailed mainboard pictures. I haven't searched for schematics of this one yet. Regards from Lisbon lynx

Rebuilding coreboot image generation
by Patrick Georgi 24 Nov '15

24 Nov '15

Hey coreboot folks, I'm looking for an approach to make building Chrome OS style coreboot images easier to do with regular coreboot tools, instead of the rather large post-processing pipeline we have in the Chrome OS build system. The rationale is that we also push the Chrome OS capabilities (eg. verified boot) upstream, and actually using them shouldn't depend on checking out yet another custom build environment. I wrote a proposal on how to do that, which can be found and commented at https://docs.google.com/document/d/1o2bFl5HCHDFPccQsOwa-75A8TWojjFiGK3r0yeI… If this is to be implemented, I'd do that as part of coreboot's build system, and work on supporting the regular image types (with a "simple" bootblock and a fallback/normal switch configuration) we currently have. I appreciate comments and concerns how this fits in with other use cases. Thanks, Patrick -- Google Germany GmbH, ABC-Str. 19, 20354 Hamburg Registergericht und -nummer: Hamburg, HRB 86891, Sitz der Gesellschaft: Hamburg Geschäftsführer: Matthew Scott Sucherman, Paul Terence Manicle

FSP 1.0 moves entire CAR region while coreboot only moves the CAR_GLOBALs proper.
