Subject: drm/radeon/kms: add ucode loader for cayman
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b8253ce204ad9fcd2aec315066492dfbc73e409;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drm/radeon/kms: add ucode loader for cayman

The MC ucode is no longer loaded by the vbios
tables as on previous asics.  It now must be loaded
by the driver.
