[PATCH v4 0/9] ARM: RPi5: Enable PCIe

[Torsten Duwe]

Basic PCIe support for the RPi5. This is the prerequisite for PCIe
slot adapters / HATs and NVMe storage. Those might require their own
supporting drivers or changes.

Changes from v3:
  - differentiate only between bcm2711 and -12. No possible future
    extensions for other chips. In particular, keep EXT_CFG_INDEX and
    EXT_CFG_DATA offsets fixed, no functions in the cfg struct that
    are the same for both, like bridge_sw_init_set and rc_mode.
  - pass error codes through the newly introduced reset call chain
  - some patches Reviewed-by Neil Armstrong

Changes from v2:
  - fix wrong subject prefixes
  - make reset drivers only found on the RPi5 depend on ARCH_BCM283X
  - some patches Reviewed-by Peter Robinson

Changes from v1:
  - fixed inbound window rewrite, which broke RPi4
  - series Tested-by Pedro Falcato
