2024-05-23device: drop unnecessary CHECK_REV_IN_OPROM_NAME optionFelix Held
The CHECK_REV_IN_OPROM_NAME Kconfig option was introduced to solve the problem of the PCI VID/DID combination of the Picasso iGPU not being sufficient information to know which VGA BIOS file to run, so a new function that additionally checks the PCI revision of that device was introduced. Later it turned out that there might be a case where even that isn't sufficient, so the soc_is_raven2() function is used in the remap function to always use the correct VBIOS file. Picasso is the only SoC that selected the CHECK_REV_IN_OPROM_NAME Kconfig option, so all other SoCs are unaffected by this change. Now that we use the VBIOS images with only the PCI VID and DID in the CBFS file name for Picasso, SeaBIOS will find the VBIOS with the same ID as the iGPU in CBFS and we don't need the workaround to add a third VBIOS image via VGA_BIOS_DGPU_* that has the name that SeaBIOS expects. This will result in SeaBIOS now running the VBIOS that has the same PCI VID/DID as the hardware which will be the wrong one in the RV2 silicon showing the PCO silicon PCI VID/DID, but that was also the case with the VGA_BIOS_DGPU_* workaround where the board's Kconfig just selected one of the two possible images during build time and hoped that it was the correct one for that actual hardware. The only board where this patch might cause a regression compared to the old behavior is the AMD Cereme reference board with Pollock APU, but I'm not even sure if any coreboot developer still has one of those boards, so I'm willing to accept that. To properly solve the problem with SeaBIOS using the correct VBIOS file in all cases, we'd need to generate that info during coreboot runtime and somehow pass it to SeaBIOS, but that's out of scope for this patch. TEST=On Mandolin with PCO silicon, the display output in both SeaBIOS and Ubuntu still works. Booting Windows 10 via the pre-built EDK2 payload that I'm using also resulted in the display output working.

2023-03-31soc/amd/picasso/graphics: use RAVEN2_VBIOS_REV with RAVEN2_VBIOS_VID_DIDFelix Held
In order for the code to find the correct VBIOS file in CBFS, remap the revision ID in the RAVEN2_VBIOS_VID_DID case to the one that matches the CBFS file name. This will make the code work as expected on devices with the PCI ID RAVEN2_VBIOS_VID_DID and a revision != RAVEN2_VBIOS_REV.

Refactor map_oprom_vendev_rev as a preparation to also remap the revision ID in the RAVEN2_VBIOS_VID_DID case.

2020-06-14soc/amd/picasso/graphics: implement map_oprom_vendev_revMartin Roth
Picasso, Dali, and Pollock iGPU share the same PCI device ID, but need different video BIOSes. This checks the vendor & device IDs along with the revision and selects the correct video BIOS to use. Also add the second VGA BIOS for Raven2-based SoCs and change all VGA BIOS IDs to the format including the revision number. Since SeaBIOS still expects the CBFS file name without the revision ID, it won't find the VBIOS any more. As a temporary workaround add the VBIOS for the silicon it will run on as VGA_BIOS_DGPU_*.
