[RFC PATCH v1 00/20] Introduce support for Raspberry PI 5.

[Oleksii Moisieiev]

This patch series provides generic support for Raspberry PI 5 in
U-Boot with additional hardware drivers.
The following features were implemented:
1) add generic board config for Raspberry PI5 including device-tree
files;
2) add support for RP1 chip with additional hardware;
3) add support for rp1-clock driver with dt-bindings update;
4) PCIE BRCMSTB driver support for Raspberry PI 5;
5) add clock/reset/gpio drivers;
6) add ethernet support in u-boot.

This patch-series introducing the basic set of supported drivers in
U-Boot which allows using such features as tftp and\or NFS.
I've posted this patch series as RFC because of the following commit:
e51ca0d221 (HACK: drivers: mfd: set bar configuration for RP1 driver, 2024-05-21)

It includes HACK for rp1 driver in u-boot. This HACK is setting bar
address in the correct order because RP1 driver in Linux Kernel rely on
the pci BAR configuration which initializes BARs based on BAR size.
This results the Linux set BARs in the same order on each boot.
U-boot does initialization without any sorting so the configuration
may be different from the Linux kernel.
BAR address configuration is set to match the Linux Kernel order
to avoid fails on address translation.

This should be changed after upstreaming RP1 driver to the Linux kernel
mainline.

Probably somebody from Raspberry will post an advise about how this
can be properly done.
U-Boot support for Raspberry PI 5 was added in terms of the following
project: https://github.com/xen-troops/meta-xt-prod-devel-rpi5
This is xen-based dom0less system on the Raspberry PI 5 with Zephyr as
Control Domain and Linux is Driver Domain.

It is Yocto-based so it will be easy to build it on your side. Please
visit link for the details.
