[Qemu-devel] [PATCH v1 00/17] ARM big-endian and setend support

[Peter Crosthwaite <crosthwaitepeter@gmail.com>]

Hi All,

This patch series adds system-mode big-endian support for ARM. It also
implements the setend instruction, and loading of BE binaries even in
LE emulation mode.

Based on Paolo's original work. I have moved all the BE32 related work
to the back of the series. Multiple parties are interested in the BE8
work just on its own, so that could potentially be merged w/o BE32.
PMM requested BE32 be at least thought out architecturally, so this
series sees BE32 functionality through.

I have tested all of LE. BE8 and BE32 in both linux-user mode (for
regressions) and system mode (BE8 and BE32 are new here).
My test application is here, the README gives some example command
lines you can run:

Regards,
Peter
