- Move branding/Heads/bootsplash-1024x768.jpg -> branding/Heads/bootsplash.jpg (We don't care about the size. Make filename generic)
- Adapt all coreboot configs so bootsplash is adapted by BRAND_NAME CONFIG_BOOTSPLASH_FILE="@BRAND_DIR@/bootsplash.jpg"
- Reminders :
- Makefile changes Heads to defined BRAND_NAME in board config
- Makefile changes -e 's!@BRAND_DIR@!$(pwd)/branding/$(BRAND_NAME)!g'
- nv41/nv50
- coreboot oldefconfigs adapted by:
- make BOARD=nitropad-ns50 coreboot.modify_and_save_oldconfig_in_place
- make BOARD=nitropad-nv41 coreboot.modify_and_save_oldconfig_in_place
- linux oldefconfigs adapted by
- make BOARD=nitropad-nv41 linux.modify_and_save_oldconfig_in_place
- since this is shared config across nv41/ns50: it only needs to be done for a single board

Squash of #1502 + moving logo/bootsplash files under branding/Heads
- Move logos and bootsplashes from blobs to branding/Heads/
- Makefile: add support for BRAND_DIR which depends on BRAND_NAME which defaults to Heads if no branding
- Boards coreboot configs: change bootsplash directory to depend on BRAND_DIR (instead of BLOBS_DIR) in bootsplash enabled configs
- Branding/Heads/bootsplash-1024x768.jpg points to branding/Heads/d-wid-ThePlexus_coreboot-linuxboot-heads_background-plain_DonateQrCode.jpg
- xcf file deleted. Original still under #1502 to reuse for modification without recompressing (blobs/heads.xcf)
- CREDITS file created to point to original authors, remixers (Open for details)
- Thanks to: @d-wid for remixing Bing's AI generated Janus logo, @ThePlexus for Qubes Box concept and @ThrillerAtPlay for its matrix background
- intel igpu related - remove i915drmfb hacks and use simplefb and libgfxinit enabled fb
- coreboot 4.19: add patch to fix https://ticket.coreboot.org/issues/500. fbwhiptail still tears screen if in native 1366x769 though
- coreboot 4.19: add patch to enable linux tampoline handle coreboot framebuffer (merged https://review.coreboot.org/c/coreboot/+/76431)
- coreboot 4.19: add patch to enable coreboot to apply jpeg voodoo to create bootsplash.jpeg injected in cbfs at build time + CircleCI apt imagemagick
- (Thanks Nico Huber @icon again for above patches!)
- coreboot configs: adapt VESAFB/LIBGFXINIT to use maximum fb height/width
- coreboot configs for iGPU only: CONFIG_LINEAR_FRAMEBUFFER_MAX_HEIGHT CONFIG_LINEAR_FRAMEBUFFER_MAX_WIDTH to native size
- coreboot configs for dGPU based on Optional VBIOS injected: VESAFB set to 1280x1024 (maximum possible).
Details:
coreboot configs: remove CONFIG_LINUX_COMMAND_LINE="drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0"
- Those were needed to expose i915drmfb driver prior of efifb working.
Remove CONFIG_NO_GFX_INIT from configs having CONFIG_NORTHBRIDGE_INTEL_SANDYBRIDGE=y
Add CONFIG_BOOTSPLASH_IMAGE from configs having CONFIG_NORTHBRIDGE_INTEL_SANDYBRIDGE=y
Add CONFIG_LINEAR_FRAMEBUFFER from configs having CONFIG_NORTHBRIDGE_INTEL_SANDYBRIDGE=y
Set BOOTSPLASH parameters to match bootsplash and jpeg requirements
+CONFIG_LINEAR_FRAMEBUFFER_MAX_HEIGHT=768
+CONFIG_LINEAR_FRAMEBUFFER_MAX_WIDTH=1024
+CONFIG_BOOTSPLASH=y
Others paramaters defined per board default setting with coreboot.save_oldconfig_in_place helper
- add additional kernel boot params for i915 where needed:
- adds : drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0 ( to permit kexec into vesa fb of kexec'ed kernel for i915 driven gpus without framebuffer compression, leaking smem fbdev address for kexec to pickup )
The calculations outlined at https://github.com/osresearch/heads/pull/1282#discussion_r1072473677
Sums to having 'ifdtool -f layout.txt ifd_shrinked.bin && cat layout.txt'
The example for T440p:
00000000:00000fff fd
00021000:00bfffff bios
00003000:00020fff me
00001000:00002fff gbe
Here: 00bfffff-00021000=BDEFFF
Which is exact result of @rbeslow's calculations.
There is an issue on haswell, maybe because of car, maybe because of non native memory init blob.
But this is not the case for xx20/xx30 boards.
This makes configs much less dependent on directory layout.
As of this commit the following variables are supported:
* @BOARD_BUILD_DIR@ - absolute path under build/
* @BLOB_DIR@ - absolute path to blobs/

This commit adds support for the t530 and w530 boards to enable dGPUs. dGPU's are required for DisplayPort external displays in the t530 dgpu model, and for both the VGA dn DisplayPort external displays in the W530 (which has two dGPUs, the K1000M and K2000M, hence two boards). The commit does the following:
1. Adds automated extraction scripts for vbios modelled on the me script in the blobs directory (one per board is necessary as it is based on board-specific bios updates).
2. Adds specific boards for the various dGPU models and corresponding coreboot configs.
3. Updates circleci config.yaml to run scripts and test boards.
Tested and working on T530 dgpu and W530 K1000M. dGPU scripts tested on Debian 10 and Ubuntu 21.04
