Before device-tree, the device serial number used to be passed to the kernel
using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
should now be done using device-tree. Thus, this passes the serial-number
property to the kernel using the serial-number property of the root node, as
expected by the kernel.The serial number is a string that somewhat represents the device's serial
number. It might come from some form of storage (e.g. an eeprom) and be
programmed at factory-time by the manufacturer or come from identification
bits available in e.g. the SoC.Signed-off-by: Paul Kocialkowski

Commit 9cc36a2 'dm: core: Add a flag to control sequence numbering' changed
the default uclass behaviour to not support bus numbering. This is incorrect
for PCI and that commit should have enabled the flag for PCI.Enable it so that PCI buses can be found and the 'pci' command works again.
Also add a test for this.Signed-off-by: Simon Glass

Baytrail physically maps the first 2 GB of SDRAM from 0x0 to 0x7FFFFFFF
and additional SDRAM is mapped from 0x100000000 and up. There is a
physical memory hole from 0x80000000 to 0xFFFFFFFF for other uses.
Because of this, PCI region 3 should only try to use up to the amount of
SDRAM or 0x80000000, which ever is less.Signed-off-by: Andrew Bradford

Writing 0xcb to I/O port 0xb2 (Advanced Power Management Control) causes

Although the two qemu-x86 targets (i440fx and q35) share a lot in

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.Signed-off-by: Bin Meng

QEMU always decode legacy IDE I/O ports on PIIX chipset. However Linux ata_piix

PIRQ routing is pretty much common in Intel chipset. It has several
PIRQ links (normally 8) and corresponding registers (either in PCI
configuration space or memory-mapped IBASE) to configure the legacy
8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing
support using device tree and move it to a common place, so that we
can easily add PIRQ routing support on a new platform.Signed-off-by: Bin Meng
