Oh, that's interesting, I've been told that the r2d machine does not work in
big endian mode:

But yes, your binaries apparently work there, so sorry for the confusion.
I'll send a patch to revert the removal.

And here's me recentish-ly debugging an issue via it:
https://landley.net/notes-2024.html#24-05-2024
(Compile/test cycles are WAY easier there than copying files onto an sd card
to test on actual hardware.)
There was a big-endian issue breaking r2d last year, but it also broke big
endian mips and some other targets too, and it got fixed. The binary I built
a few months ago was working fine for me with vanilla qemu git source? (I
don't _think_ I had local changes?) I can try to build the version removed
to check that...
Yes I should be better about pushing local patches upstream. For example,
here's the kernel patch I use to run fdpic binaries under qemu:
https://landley.net/bin/mkroot/latest/linux-patches/0002-sh4-fdpic.patch
Which lets you enable the FDPIC loader on an mmu kernel, which is useful for
testing j-core userspace under qemu.
