ThunderX PCIe controller to off-chip devices (so-called PEM) is not fully compliant with ECAM standard. It uses non-standard configuration space accessors (see thunder_pem_ecam_ops) and custom configuration space granulation (see bus_shift = 24). In order to access configuration space and probe PEM as ACPI-based PCI host controller we need to add MCFG quirk infrastructure. This involves: 1. A new thunder_pem_acpi_init() init function to locate PEM-specific register ranges using ACPI. 2. Export PEM thunder_pem_ecam_ops structure so it is visible to MCFG quirk code. 3. New quirk entries for each PEM segment. Each contains platform IDs, mentioned thunder_pem_ecam_ops and CFG resources. Quirk is considered for ThunderX silicon pass2.x only which is identified via MCFG revision 1. ThunderX pass 2.x requires the following accessors: NUMA Node 0 PCI segments 0- 3: pci_generic_ecam_ops (ECAM-compliant) NUMA Node 0 PCI segments 4- 9: thunder_pem_ecam_ops (MCFG quirk) NUMA Node 1 PCI segments 10-13: pci_generic_ecam_ops (ECAM-compliant) NUMA Node 1 PCI segments 14-19: thunder_pem_ecam_ops (MCFG quirk) [bhelgaas: adapt to use acpi_get_rc_resources(), update Makefile/ifdefs so quirk doesn't depend on CONFIG_PCI_HOST_THUNDER_PEM] Signed-off-by: Tomasz Nowicki <tn@semihalf.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
