a2dc818f21 armv8/ls2085a: Expose all DDR region(s) to Linux
This patch allows u-boot to expose the complete DDR region(s) to Linux
(after subtracting the memory hidden via MEM_TOP_HIDE mechanism).

This allows the u-boot to support the 48-bit VA support provided by
ARM64 Linux in flavors 3.18 and above, by passing the appropriate
'memory' DTS nodes.

expansion ROM address. To fix this, we should configure the
ROM address during the auto config process.

cdb6babec6 x86: queensbay: Change PCIe root ports' interrupt routing
So far interrupt routing works pretty well for any on-chip devices
on Intel Crown Bay. When inserting any PCIe card to any PCIe slot,
Linux kernel is smart enough to do interrupt swizzling and figure
out device's irq using its parent bridge's interrupt routing info
all the way up to its root port. In U-Boot all PCIe root ports'
interrupts were routed to PIRQ E/F/G/H before, while actually all
PCIe downstream ports received INTx are routed to PIRQ A/B/C/D
directly and not configurable. Now we change this mapping so that
any external PCIe device can work correctly.

07545d861c x86: Generate a valid MultiProcessor (MP) table
Implement write_mp_table() to create a minimal working MP table.
This includes an MP floating table, a configuration table header
and all of the 5 base configuration table entries. The I/O interrupt
assignment table entry is created based on the same information used
in the creation of PIRQ routing table from device tree. A check
duplicated entry logic is applied to prevent writing multiple I/O
interrupt entries with the same information.

Use a Kconfig option GENERATE_MP_TABLE to tell U-Boot whether we
need actually write the MP table at the F seg, just like we did for
PIRQ routing and SFI tables. With MP table existence, linux kernel
will switch to I/O APIC and local APIC to process all the peripheral
interrupts instead of 8259 PICs. This takes full advantage of the
multicore hardware and the SMP kernel.
