+Subject: [PATCH 4324/4736] drm/amdgpu: Add PSP loading support for DMCUB ucode
+
+DMCUB ucode requires secure loading through PSP. This is already
+supported in PSP as GFX_FW_TYPE_DMUB, it just needs to be mapped from
+AMDGPU_UCODE_ID_DMCUB to GFX_FW_TYPE_DMUB.
+
+DMUB is a shorthand name for DMCUB and can be used interchangeably.
