60878e753c rpi5: Use devicetree as alternative way to read IO base addresses 
MBOX and Watchdog on RPi5/bcm2712 have a different base IO offsets.
Find them via devicetree blob passed by bootloader.

814e1a4b8c rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM 32bit) 
Create a non-cacheable mapping for the 0x600000000 physical memory region,
where MMIO registers for the PCIe XHCI controller are instantiated by the
PCIe bridge. Due to 32bit limit in the CPU virtual address space in ARM
32bit mode, this region is mapped at 0xff800000 CPU virtual address.

8e3361c88a ARM: bcm283x: Move BCM283x_BASE to a global variable 
We move the per SOC define BCM283x_BASE to a global variable.
This is a first step to provide a single binary for several bcm283x
SoCs.
