[PATCH 0/3] gdbstub: add support for switchable endianness

[Changbin Du]

To resolve the issue to debug switchable targets, this serias introduces
basic infrastructure for gdbstub and enable support for ARM and RISC-V
targets.

For example, now there is no problem to debug an big-enadian aarch64 target
on x86 host.

  $ qemu-system-aarch64 -gdb tcp::1234,endianness=big ...

Changbin Du (3):
  gdbstub: add basic infrastructure to support switchable endianness
  arm: gdbstub: add support for switchable endianness
  riscv: gdbstub: add support for switchable endianness
