Hi Linus!
The sh updates for v6.5 introduced multiple regressions that this pull request addresses.
In particular, the change a8ac2961148e ("sh: Avoid using IRQ0 on SH3 and SH4") causes
several boards to hang during boot due to incorrect IRQ numbers.
Geert Uytterhoeven has contributed patches that handle the virq offset in the IRQ code
for the dreamcast, highlander and r2d boards while Artur Rojek has contributed a patch
which handles the virq offset for the hd64461 companion chip.
With the series applied, the affected boards will boot the kernel again without issues.
The following changes since commit 7497840d462c8f54c4888c22ab3726a8cde4b9a2:
sh: Provide unxlate_dev_mem_ptr() in asm/io.h (2023-07-05 19:04:51 +0200)

Apparently, booting on dreamcast currently does not work even with the patches applied due
to unreleated issues. So, please drop the last paragraph from the pull message to avoid
confusion.
Thanks,
