Re: [PATCH 1/1] pci: definition of pci_addr_t and pci_size_t

Hi Heinrich,

Currently the size of pci_addr_t and pci_size_t depends on CONFIG_SYS_PCI_64BIT. For qemu_arm64_defconfig with 4 GiB RAM this leads to an error

pci_hose_phys_to_bus: invalid physical address

which is due to the truncation of the bus address in _dm_pci_phys_to_bus.

Defining CONFIG_SYS_PCI_64BIT is not a solution as this results in an error

PCI: Failed autoconfig bar 10

So let's use unsigned long for pci_addr_t and pci_size_t.

But how will this work on x86 where we might have 32-bit U-Boot but need 64-bit PCI addresses?
