Add initial version of the Broadcom iProc PCIe driver. This driver

The driver also supports MSI

The driver looks suspiciously like the one that Hauke already submitted a
while ago for bcm53xx. Please come up with a merged driver that works for
both.
Could you please be a little more specific. What driver did "Hauke already submitted"? I do not see any driver in the kernel you are talking about.

Are you sure that iProc isn't based on the BCMA bus infrastructure after
all? Even the physical address of your PCI host falls into the address
range that is used for the internal BCMA bus on the other chips!
BCMA seems to be for MIPS architectures. It seems to be quite specific to those architectures using BCMA. I see no use of it in bcm53xx code?
