In my personal code base (git://repo.or.cz/qemu/ar7.git), I had removed
lots of TARGET_WORDS_BIGENDIAN some years ago when I started
code changes to combine MIPS big and little endian in one executable
(still unfinished :-(, sorry).
I added a 'bool bigendian' to CPUArchState.
Richard, MIPS can be added to your list of architectures which might
profit from your proposed changes.
Regards,
Stefan
