60ee60944b pci: ensure enumeration of all devices in pci_init
Use the uclass_first_device_check and uclass_next_device_check functions
instead of uclass_first_device and uclass_next_device in pci_init. This
ensures that all PCI devices are tried to be probed. Currently if a
device fails to probe, the enumeration stops and the devices which come
after the failed device are not probed.

5fafd7e35f pci: Avoid assigning PCI resources that are below 0x1000
commit b7598a43f2 ("[PATCH] Avoid assigning PCI resources from
zero address") only moved the bus lower address to 0x1000 if the
given bus start address is zero. The comment said 0x1000 is a
reasonable starting value, hence we'd better apply the same
adjustment when the given bus start address is below 0x1000.

52ba907328 PCI: dm: Ignore 64-bit memory regions if CONFIG_SYS_PCI_64BIT not set
Currently, qemu_arm_defconfig and qemu_arm64_defconfig only work with
the 'highmem=off' parameter passed to QEMU's virt machine. The reason is
that when 'highmem' is not disabled, QEMU appends 64-bit a memory
resource to the PCI controller's regions property in DT in addition to
the 32-bit PCI memory window in low memory. And the current DT parsing
code picks the last (thus the 64-bit one) memory resource, whose address
eventually gets silently truncated to 32 bits because
CONFIG_SYS_PCI_64BIT is not set, which obviously causes PCI to break.

Avoid this problem by ignoring memory regions whose addresses are above
the 32-bit boundary when CONFIG_SYS_PCI_64BIT is not set.

355560d588 pci: tegra: introduce weak tegra_pcie_board_port_reset() function
Introduce a weak tegra_pcie_board_port_reset() function by default
calling the existing tegra_pcie_port_reset() function. Additionally add
a tegra_pcie_port_index_of_port() function to retrieve the specific PCIe
port index if required. This allows overriding the PCIe port reset
functionality from board specific code as e.g. required for Apalis T30
and Apalis TK1.

e097ce4304 pci: Don't use pci_indirect when DM is active
Declaration of indirect PCI bridges is not compatible with DM: Both
define PCI operations, but in different ways. Hence, don't use indirect
bridges if DM is active.
