Subject: hw/i386: Mark devices as little-endian
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a115ab5ba30ae78efdf346df594940042b69aa27;p=qemu.git

hw/i386: Mark devices as little-endian

These devices are only used by the X86 targets, which are only
built as little-endian. Therefore the DEVICE_NATIVE_ENDIAN
definition expand to DEVICE_LITTLE_ENDIAN (besides, the
DEVICE_BIG_ENDIAN case isn't tested). Simplify directly using
DEVICE_LITTLE_ENDIAN.
