Move the XHCI PCI device base up in the virtual address space. This fixes
|
||||
initialization failure observed with newer Raspberry Pi firmware, later
|
||||
than 63b1922311 ("firmware: arm_loader: Update armstubs with those from
|
||||
PR 117). It looks that chosing 0xff800000 as the XHCI PCI device base
|
||||
conflicts with the updated ARM/VideoCore firmware.
|
||||
|
||||
This also requires to reduce the size of the mapped PCI device region
|
||||
from 8MiB to 4MiB to fit into 32bit address space. This is still enough
|
||||
for the XHCI PCI device.

The RPI firmware adjusts several property values in the dtb it passes
|
||||
to u-boot depending on the board/SoC revision. Inherit some of these
|
||||
when u-boot loads a dtb itself. Specificaly copy:
|
||||
|
||||
* /model: The firmware provides a more specific string
|
||||
* /memreserve: The firmware defines a reserved range, better keep it
|
||||
* emmc2bus and pcie0 dma-ranges: The C0T revision of the bcm2711 Soc (as
|
||||
present on rpi 400 and some rpi 4B boards) has different values for
|
||||
these then the B0T revision. So these need to be adjusted to boot on
|
||||
these boards
|
||||
* blconfig: The firmware defines the memory area where the blconfig
|
||||
stored. Copy those over so it can be enabled.
|
||||
* /chosen/kaslr-seed: The firmware generates a kaslr seed, take advantage
|
||||
of that.
