[Qemu-arm] [PATCH v2 00/18] 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 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

Changed since v1:
Addressed PMM review
Added doc comments to new/changed loader.h APIs


Paolo Bonzini (8):
  linux-user: arm: fix coding style for some linux-user signal functions
  linux-user: arm: pass env to get_user_code_*
  target-arm: implement SCTLR.B, drop bswap_code
  linux-user: arm: handle CPSR.E correctly in strex emulation
  target-arm: pass DisasContext to gen_aa32_ld*/st*
  target-arm: introduce disas flag for endianness
  target-arm: implement setend
  target-arm: implement BE32 mode in system emulation

Peter Crosthwaite (10):
  target-arm: cpu: Move cpu_is_big_endian to header
  arm: cpu: handle BE32 user-mode as BE
  linux-user: arm: set CPSR.E/SCTLR.E0E correctly for BE mode
  target-arm: implement SCTLR.EE
  target-arm: a64: Add endianness support
  target-arm: introduce tbflag for endianness
  loader: add API to load elf header
  loader: load_elf(): Add doc comment
  loader: Add data swap option to load-elf
  arm: boot: Support big-endian elfs
