    KMS support by Dave Airlie <airlied@redhat.com>.
    
    For Radeon 100- to 500-series, firmware blobs look like:
        struct {
            __be32 datah;
            __be32 datal;
        } cp_ucode[256];
    
    For Radeon 600-series, there are two separate firmware blobs:
        __be32 me_ucode[PM4_UCODE_SIZE * 3];
        __be32 pfp_ucode[PFP_UCODE_SIZE];
    
    For Radeon 700-series, likewise:
        __be32 me_ucode[R700_PM4_UCODE_SIZE];
        __be32 pfp_ucode[R700_PFP_UCODE_SIZE];
