[PATCH v1 1/4] hw/arm: Remove ast2700a0-evb machine

Jamin Lin via posted 4 patches 5 months, 1 week ago
There is a newer version of this series
[PATCH v1 1/4] hw/arm: Remove ast2700a0-evb machine
Posted by Jamin Lin via 5 months, 1 week ago 
The ast2700a0-evb machine represents the first revision of the AST2700 and
serves as the initial engineering sample rather than a production version.
A newer revision, A1, is now supported, and the ast2700a1-evb should replace
the older A0 version.

We need to wait *two* releases after deprecation before removing a
machine or any other feature. So removal of the ast2700a0-evb machine
will be possible for QEMU 11.0 (next after QEMU 10.2).

File docs/about/removed-features.rst should be updated too.

The "ast2700-evb" alias should be moved first to the ast2700a1_evb machine.
This can be done in this QEMU cycle


Thanks,
