Subject: prep: Make System I/O port 0092 read/write
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b6f54b31e7cfb2e88b76fc6cfc5334a26d1b9e53;p=qemu.git

prep: Make System I/O port 0092 read/write

Port 0x0092 is documented as read/write, so for now return the
endianness state instead of hardcoded 0x00.
