Hello build bot (Jenkins), Subrata Banik, Angel Pons, Nick Vaccaro,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/62384
to look at the new patch set (#4).
Change subject: mb/google/brya/var/agah: Add GPU power sequencing
......................................................................
mb/google/brya/var/agah: Add GPU power sequencing
This patch adds support for power sequencing of the Nvidia GN3050 for
agah, which uses PCH GPIOs to control the 5 power rails required for
the GPU. The GPU is power sequenced on during mainboard
initialization, then it is enumerated on the PCI bus and its resources
are assigned. This GPU will be used in a sort of "hybrid graphics"
mode, therefore during finalization, since its PCI BARs are saved into
ACPI memory and the GPU is not required upon initial boot, the GPU is
power sequenced off.

PS2, Line 79: for
> So you are dropping the for loop.... We need that for the zork/picasso/dali platforms. […]
For picasso soc, each microcode variant will be in its own file (cpu_microcode_8180.bin, cpu_microcode_8181.bin, and cpu_microcode_8201.bin). There are no longer multiple microcodes in a single file, so the for loop is not needed anymore. On a given variant (8180, 8181, or 8201), it will only look up its own microcode.

Done

> Do you need the size?
Tested a timeless build with and without the size, and they were identical. Good catch, size was not needed
https://review.coreboot.org/c/coreboot/+/63589/comment/2b3bcc69_1ecaa5f2
PS2, Line 86: snprintf
> I would check the return code.
Leaving unresolved for now - I moved the code into the !cache_valid block so it only runs once.
If snprintf were to fail (it really should not here), then the cbfs_map would fail and printk below should catch it and print what happened. Same thing in the preload_microcode() function below. I'm not sure what is gained by checking the return value here.
I used https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/thi… as a reference to load a file from CBFS based on an ID in the file name.

maybe break out the `segments->len == 0` case into a boolean variable?
