Taken from : https://github.com/Nitrokey/heads/tree/temp-release-v2.3
- 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.
- add x230-maximized-fhd_edp and x230-hotp-maximized-fhd_edp board configs
- add/rework coreboot patch for x230 fhd variant to be applied on top of 4.13
- add coreboot config to point to x230-edp variant, fixing path to vbt file since default path is wrong under. Comment made upstream https://review.coreboot.org/c/coreboot/+/28950/22#message-4904ce82f01ba0505b391e072e4537b6a9f1a229
- remove no gfx init and replace with libgfxinit(defonfig default), set internal display as default
- add x230-hotp-maximized-fhd_edp and x230-maximized-fhd_edp to CircleCI builds
- One single shared coreboot config between boards/x230-hotp-maximized-fhd_edp/x230-hotp-maximized-fhd_edp.config and boards/x230-maximized-fhd_edp/x230-maximized-fhd_edp.config
- Coreboot 4.13 patch from coreboot at patches/coreboot-4.13/0002-x230-fhd-variant.patch
- config/coreboot-x230-maximized-fhd_edp.config points to seperate coreboot config per patch (CONFIG_BOARD_LENOVO_X230_EDP)
