[PATCH v2 0/7] fw_cfg: Run tests on big-endian

[Philippe Mathieu-Daudé]

This series allow fw_cfg tests to run on big-endian targets.

since v1 [1]:
- addressed Laszlo/Laurent/Thomas comments
- added Laszlo R-b tags

This should help us to notice regression such this one
introduced in QEMU v4.0.0:

  commit ee5d0f89de3e53cdb0dcf51acc1502b310ed3bd2
  Date:   Tue Nov 20 21:10:25 2018 -0800

    fw_cfg: Fix -boot reboot-timeout error checking

Later fixed in QEMU v4.1.0:

  commit 04da973501b591525ce68c2925c61c8886badd4d
  Date:   Wed Apr 24 07:06:41 2019 -0700

    hw/nvram/fw_cfg: Store 'reboot-timeout' as little endian

And older one that required manual testing [2], such:

  commit 36b62ae6a58f9a588fd33be9386e18a2b90103f5

    fw_cfg: fix endianness in fw_cfg_data_mem_read() / _write()
