Aaron Durbin	76c3700f02	haswell: Add initial support for Haswell platforms The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore, the southbridge support is included as well. The basis for this code is the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires more attention, but this is a good starting point. This code partially gets up through the romstage just before training memory on a Haswell reference board.

haswell: fix ACPI MCFG table

The acpi_fill_mcfg() was still using ivy/sandy PCI device ids which Hawell
obviously doesn't have. This resulted in an empty MCFG table. Instead of
relying on PCI device ids use dev/fn 0/0 since that is where the host
bridge always resides. Additionally remove the defines for the IB and SB
pci device ids. Replace them with mobile and ult Haswel device ids and
use those in the pci driver tables for the northbridge code.

Booted to Linux and noted that MCFG was properly parsed.

haswell: resource allocation

The previous code w.r.t. resource allocation was getting lucky
based on the way fixed mmio resources on the system were being
chosen. Namely, PCIEXBAR was the lowest mmio space and the other
fixed non-standar BARs were above it. The resource allocator would
then start allocating standard BARs below that.

On top of that other resources were being added when
dev_ops->set_resources() was being called on the PCI domain. At that
point the PCI range limit were already picked for where to start
allocating from.

To ensure we no longer get lucky during resource allocation add the
fixed resources in the host bridge and add the memory controller
cacheable memory areas. With those resources added the range limit
for standard PCI BARs is chosen properly.

Depending on haswell board configurations we may need to adjust and
pass in the size of physical address space needed for PCI resources
to the reference code. For the time being the CRBs appear to be OK.

Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.

haswell: Add initial support for Haswell platforms

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,
the southbridge support is included as well. The basis for this code is
the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires
more attention, but this is a good starting point.

This code partially gets up through the romstage just before training
memory on a Haswell reference board.
