[ANN] U-Boot v2023.01-rc2 released

Hey all,

Getting back on schedule, here's -rc2. We're getting well in to the stabilization period now, but there's still some things I would like to see come in including a net PR.

In terms of a changelog, git log --merges v2023.01-rc1..v2023.01-rc2 contains what I've pulled but as always, better PR messages and tags will provide better results here.

Looking forward, the schedule is for now rcs every other Monday, and with final release on January 9th, 2023. Thanks all!
