[Qemu-devel] [PATCH v2 0/5] Add aarch64_be-linux-user target

[Michael Weiser]

Hello,

below patches add support for big-endian aarch64 to linux-user. Almost
everything is already in place. The patches just set up the CPU flags as
required for big-endianess, add a distinction in uname and make sure the
instructions for the signal trampoline end up in memory little-endian.
Finally, configure is extended to allow building of a
aarch64_be-linux-user target and scripts/qemu-binfmt-conf.sh to include
the binfmt magic for aarch64_be ELF files.

With this I am able to run individual aarch64_be binaries as well as
chroot into a full-blown aarch64_be userland using binfmt_misc, running
and compiling things (Gentoo crossdev/native).

v2:
- add binfmt magic to qemu-binfmt-conf.sh
- fix style problems (tab indenting)

Thanks,
Michael
