* x86: qemu: Adjust VGA initializationBin Meng2015-06-04-0/+2
| | | | | | | | | | | | | As VGA option rom needs to run at C segment, although QEMU PAM emulation seems to only guard E/F segments, for correctness, move VGA initialization after PAM decode C/D/E/F segments. Also since we already tested QEMU targets to differentiate I440FX and Q35 platforms, change to locate the VGA device via hardcoded b.d.f instead of dynamic search for its vendor id & device id pair.

* x86: qemu: Enable legacy IDE I/O ports decodeBin Meng2015-06-04-0/+19
QEMU always decode legacy IDE I/O ports on PIIX chipset. However Linux ata_piix driver does sanity check to see whether legacy ports decode is turned on. To make Linux ata_piix driver happy, turn on the decode via IDE_TIMING register. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
