mhorne created this revision.

I also added SMP support to Unleashed board. But that may not be notable change :)

@br maybe something like this?

ok

Note that the notes only document changes from the most recent release (in this case 12.2) to 13.0, not 12.0 to 13.0, so some of these aren't relevant. I wonder if the OpenSBI support made it into 12.2? If not, it warrants a mention I think. Hmm, 12.2 did include support for booting via OpenSBI v0.7.

This was already present in 12.2.

This was already present in 12.2.

I thought SMP was supported in 12.x?

cgem(4) was in 12.2.

The remaining bits are support for the SiFive so maybe there should be a general note about support for this SoC / board?

This was in 12.2.

I think this was already present in 12.2. The release notes only document new changes since 12.2.

Hmm, you're right. This is unfortunate since nobody (as far as I know) ever really used or advertised riscv on 12 since the initial branch of 13, including the 12.2 relnotes.

Unfortunately, I ran out of steam for this ahead of the release, and the moment has passed.
