json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

The video decoding IP lies within the DOS memory region,
|
|
except for the hardware bitstream parser that makes use of an undocumented
|
|
region.
|
|
|
|
It makes use of the following blocks:
|
|
- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
|
|
then feed from this VIFIFO.
|
|
- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
|
|
- VDEC_HEVC can decode HEVC and VP9.
|
|
|
|
Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
|
|
concurrently.
