When ATI Radeon graphics card has been compiled directly into the kernel
instead of as a module, we should make sure the firmware for the model
(check available ones in /lib/firmware/radeon) is built-in to the kernel
as well, otherwise there exists the following fatal error during GPU init,
change CONFIG_DRM_RADEON=y to CONFIG_DRM_RADEON=m to fix it.

The commit message looks shocking.
You'd better reword it as "MIPS: Loongson64: Mark GPU driver as module in Kconfig"
Thanks.

OK, I will modify the patch subject and send v2.
