Thanks a lot for those fixes. Have the kernel patches been submitted
upstream, and accepted?
One issue with your change is of course that now the fix only works
when building the specific qemu_sh4 defconfigs. When not using one of
those defconfigs, but simply building the regular Linux kernel for SH4,
will lead to a kernel that no longer boots.
