Revert "PCI: designware: Program ATU with untranslated address"
Revert f4c55c5a3f7f ("PCI: designware: Program ATU with untranslated
address").
Note that dra7xx_pcie_host_init() now modifies pp->io_base, but we still
need the original value for dw_pcie_setup() in the path below, so this adds
a new io_base_tmp member. It will be removed later when dw_pcie_setup() is
removed.
dra7xx_add_pcie_port
dw_pcie_host_init
pp->io_base = range.cpu_addr
pp->io_base_tmp = range.cpu_addr # <-- added
pp->ops->host_init
dra7xx_pcie_host_init # ops->host_init
pp->io_base &= DRA7XX_CPU_TO_BUS_ADDR # <-- modified
pci_common_init_dev(..., &dw_pci)
pcibios_init_hw
hw->setup
dw_pcie_setup # hw_pci.setup
pci_ioremap_io(..., pp->io_base_tmp) # <-- original addr required
