[PATCH v6 22/45] drm/amd: Load PSP microcode during early_init

Mario Limonciello
2023-01-05T03:46:12Z

Simplifies the code so that all PSP versions will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

Any failures will cause the driver to fail to probe before the firmware
framebuffer has been removed.
