Cover letter [Qemu-arm] [PATCH v2 00/18] ARM big-endian and setend support
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 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
