Bug description:
[ Impact ]
Similar to LP: #2129011, on 6.14.0-33-generic, some GPT2-based
platforms also suffer from eDP issues caused by outdated firmware.
This has been observed on some latest HP platforms.
[ Fix ]
Update the PSP_14_0_4 bins to the latest. This includes the following
files:
1. amdgpu/psp_14_0_4_ta.bin[1]
2. amdgpu/psp_14_0_4_toc.bin[2]
[ Test ]
1. Install the kernel and the updated linux-firmware on the said GPT2
platforms.
2. Boot into the OS. The eDP should not show garbage.
2. Repeat the above steps on a platform with KRACKEN processor. The eDP
should also function normally.
[ Where the problems could occur ]
This should affect only the PSP 14.0.4 hardware. This currently
afftects the GPT2 and Krackan[3] platfroms.
