From: Florian Fainelli <f.fainelli@gmail.com> This commit adds a memory API suitable for ascertaining the sizes of each of the N memory controllers in a Broadcom STB chip. Its first user will be the Broadcom STB PCIe root complex driver, which needs to know these sizes to properly set up DMA mappings for inbound regions. We cannot use memblock here or anything like what Linux provides because it collapses adjacent regions within a larger block, and here we actually need per-memory controller addresses and sizes, which is why we resort to manual DT parsing.
