Same here.

According to this command:
--8<---------------cut here---------------start------------->8---
mathieu@meije ~/linux/drivers/gpu/drm$ grep FW_LOADER Kconfig -B 5
source "drivers/gpu/drm/arm/Kconfig"
config DRM_RADEON
tristate "ATI Radeon"
depends on DRM && PCI && MMU
select FW_LOADER
--
source "drivers/gpu/drm/radeon/Kconfig"
config DRM_AMDGPU
tristate "AMD GPU"
depends on DRM && PCI && MMU
select FW_LOADER
--
graphics card. If M is selected, the module will be called tdfx.
config DRM_R128
tristate "ATI Rage 128"
depends on DRM && PCI
select FW_LOADER
--
for this driver to work.
config DRM_MGA
tristate "Matrox g200/g400"
depends on DRM && PCI
select FW_LOADER
--8<---------------cut here---------------end--------------->8---
the radeon, amdgpu, r128 and mga DRM drivers are probably relying on
firmware loading. So we should maybe extend this patch and add the
latter two drivers, even though they are supporting really old
hardware.
Thanks,
Mathieu
