PCI/ACPI: Add generic MCFG table handling
On ACPI systems that support memory-mapped config space access, i.e., ECAM, the PCI Firmware Specification says the OS can learn where the ECAM space is from either: - the static MCFG table (for non-hotpluggable bridges), or - the _CBA method (for hotpluggable bridges) The current MCFG table handling code cannot be easily generalized owing to x86-specific quirks, which makes it hard to reuse on other architectures. Implement generic MCFG handling from scratch, including: - Simple MCFG table parsing (via pci_mmcfg_late_init() as in current x86) - MCFG region lookup for a (domain, bus_start, bus_end) tuple [bhelgaas: changelog] Signed-off-by: Tomasz Nowicki <tn@semihalf.com> Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
