[PATCH v4 0/5] ARM: arbitrary virtual-physical mappings for RPi4 XHCI support

Hi All,

This patchset adds support for creating a mapping for the arbitrary
physical address at the given virtual address. This is needed to enable
support for XHCI USB controller on PCIe bridge on Raspberry Pi 4 board,
on which the USB controller's MMIO area 0x600000000 has to be remapped
somewhere to fit in 4GiB virtual address space when running in ARM 32bit
mode.

This patchset is a continuation of the Raspberry Pi 4 XHCI/PCIe patchset:
https://patchwork.ozlabs.org/project/uboot/list/?series=179078
and the following discussion:
https://lists.denx.de/pipermail/u-boot/2020-May/411086.html

Best regards
Marek Szyprowski
Samsung R&D Institute Poland


Changelog:

v4:
- added a patch, which moves ADDR_MAP config entry to Kconfig system
  as requested by Simon Glass
- rebased onto v4 of the "USB host support for Raspberry Pi 4 board
  (64-bit)" patchset

v3: https://lists.denx.de/pipermail/u-boot/2020-May/412427.html
- fixed broken RPi3 and lack of the identity mapping for map_physmem
  (for example for the itest command was broken)
- added a patch fixing a new build warning

v2: https://lists.denx.de/pipermail/u-boot/2020-May/411765.html
- fixed ARM64 build

v1: https://lists.denx.de/pipermail/u-boot/2020-May/411765.html
- initial RFC


Patch summary:

Marek Szyprowski (4):
  powerpc: move ADDR_MAP to Kconfig
  arm: provide a function for boards init code to modify MMU
    virtual-physical map
  rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM
    32bit)
  config: Enable support for the XHCI controller on RPI4 board
