Browse Source 
Enable AMD Display Controller support for AMD Radeon GPUs on UEFI systems.
Add custom_kernel_config__enable_amd_dc() to uefi_common.inc with the
following kernel options for all UEFI boards except cloud:

- DRM_AMD_DC: AMD Display Controller
- DRM_AMD_DC_DCN: Display Core Next support
- DRM_AMD_DC_DSC_SUPPORT: Display Stream Compression

Provides proper display engine support for AMD graphics cards on x86,
arm64, and loong64 UEFI platforms.
