* x86: qemu: add fw_cfg supportMiao Yan2016-01-13-1/+287
| | | | | | | | | | | | | The QEMU fw_cfg interface allows the guest to retrieve various data information from QEMU. For example, APCI/SMBios tables, number of online cpus, kernel data and command line, etc. This patch adds support for QEMU fw_cfg interface.

* x86: tsc: Remove legacy timer codesBin Meng2015-12-01-1/+0
| | | | | | | | | | | Now that we have converted all x86 boards to use driver model timer, remove these legacy timer codes in the tsc driver. Note this also removes the TSC_CALIBRATION_BYPASS Kconfig option, as it is not needed with driver model. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* x86: qemu: Adjust VGA initializationBin Meng2015-06-04-19/+15
| | | | | | | | | | | | | 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.

| | | | | | | | | 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.
