Re: VisionFive 2 eMMC boot issues.

Quick update, i also tested v2026.04 as well, and it also boots the SD card
correctly with the same clean pattern as v2025.10/v2026.01, straight
through to GRUB and Debian, no cluster read errors. Log below.

So the regression is most likely somewhere between v2026.04 and v2026.07.

Also worth mentioning, someone else in a community also reported having the
exact same errors on v2026.07 (SD/EFI boot failure), and mentioned v2026.04
worked for them too which is why i tried it so this isn't isolated to my
board specifically.

Happy to keep looking into it this if useful, please let me know if there's
a specific commit or intermediate version i might need to test.
