Get vCPU endianness from CP0::BE bit.
Propagate endianness at the board level, using QOM property.
Remove target-specific endianness knowledge from target/.

Philippe Mathieu-Daudé (12):
  target/mips: Declare cpu_is_bigendian_env() in 'internal.h'
  target/mips: Introduce mo_endian_env() helper
  target/mips: Replace MO_TE by  mo_endian_env() in get_pte()
  target/mips: Convert mips16e decr_and_load/store() macros to functions
  target/mips: Introduce mo_endian() helper
  target/mips: Explode MO_TExx -> MO_TE | MO_xx
  target/mips: Replace MO_TE by mo_endian()
  target/mips: Expose MIPSCPU::is_big_endian property
  hw/mips/cps: Set the vCPU 'cpu-big-endian' property
  hw/mips: Have mips_cpu_create_with_clock() take an endianness argument
  target/mips: Remove target-specific code in mips_cpu_reset_hold()
  hw/mips/malta: Remove TARGET_BIG_ENDIAN #ifdef'ry

For the series:

Reviewed-by: Jiaxun Yang <jiaxun.yang@flygoat.com>
Tested-by: Jiaxun Yang <jiaxun.yang@flygoat.com>

Will this lead us to bi-endian QEMU executable?

Thanks
