If you align regardless if its 8/10bit (which I don't really mind, it
does not cost much and helps if you have a Mali GPU), please do in
rkvdec_coded_fmts[].frmsize.step_width.
Otherwise you'll endup creating a config per bit depth, and probably
won't need any of the rk format stuff, since you could just update the
config, and enumerate from there. I don't mind your method though, but
lets not hardcode alignment where it shouldn't be.

Do we want to keep this small lie ? Baseline is not supported as we
don't support FMO and ASO. That being said, in framework like
GStreamer, we try to decode anyway, cause we know we don't have a
software fallback anyway.

Should include V4L2_MPEG_VIDEO_H264_PROFILE_HIGH_10_INTRA and
V4L2_MPEG_VIDEO_H264_PROFILE_HIGH_422_INTRA too ....

Which requires substracting
V4L2_MPEG_VIDEO_H264_PROFILE_HIGH_444_PREDICTIVE too.
