[U-Boot] [PATCH 00/10] x86: Add MP support to QEMU

[Bin Meng]

This patch series mainly add MP support to QEMU as well as some
other necessary fixes for x86.

Verified by booting Linux kernel on QEMU i440FX and Q35, and make
sure I/O APIC interrupt is being used by the kernel with the help
of MP table provided by U-Boot.

This series is the prerequisite for the follow-up ACPI support
which is currently being worked on by Saket.


Bin Meng (10):
  x86: Change pci option rom area MTRR setting to cacheable
  x86: Enable DM RTC support for all x86 boards
  x86: pci: Assign pci irqs to all functions
  x86: pci: Do not assign irq 0 to pci device
  x86: mpspec: Allow platform to determine how PIRQ is connected to I/O
    APIC
  x86: mpspec: Move writing ISA interrupt entry after PCI
  x86: qemu: Enable I/O APIC chip select on PIIX3
  x86: qemu: Add MP initialization
  x86: qemu: Enable writing MP table
  x86: qemu: Turn on PCIe ECAM address range decoding on Q35
