Subject: IDE: MMIO IDE device control should be little endian
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a7044bb62ca490b8742ac17d40bb774b7a9048e;p=qemu.git

IDE: MMIO IDE device control should be little endian

Set the IDE MMIO memory type to little endian. The ATA specs identify
words part of the control commands encoded as little endian.
While this has no impact on little endian systems, it's required for big
endian systems(eg OpenRisc).
