[Qemu-devel] [PATCH v4 44/51] build-sys: add a target schema

[Marc-André Lureau]

This schema is going to contain target-specific commands/events &
types, that can be conditionnally guarded with poisoned defines.

And new rules to compile the schema generated files per-target, using
the 'target' unit name filter.

This new schema is now the top-level schema to generate the
documentation (to include also target-specific commands/types).
