[PATCH v6 17/45] drm/amd: Load GFX10 microcode during early_init
From: Mario Limonciello
Date: Wed Jan 04 2023 - 22:45:50 EST
Simplifies the code so that GFX10 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.
