33166054c7 arm: rpi: perform XHCI firmware upload only once
XHCI firmware upload must be performed only once after initializing the
PCI bridge. This fixes USB stack initialization after calling "usb stop;
usb start" on Raspberry Pi 4B.

d774da08dc arm: rpi: Add function to trigger VL805's firmware load
On the Raspberry Pi 4, after a PCI reset, VL805's (a xHCI chip) firmware
may either be loaded directly from an EEPROM or, if not present, by the
SoC's VideCore (the SoC's co-processor). Introduce the function that
informs VideCore that VL805 may need its firmware loaded.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

8ae1f82988 mmc: use core clock frequency in bcm2835 sdhost
In raspberrypi-firmware 7fdcd00e00a42a1c91e8bd6f5eb8352fe9358557 and
later start.elf now sets the EMMC clock to 200 MHz.

According to Phil Elwell in
https://github.com/raspberrypi/firmware/issues/953
the SDHost controller shares the core/VPU clock and doesn't use
the EMMC clock.

Use the core clock id when determining the frequency to allow
U-Boot to work with recent versions of raspberrypi-firmware.
Otherwise U-Boot hangs at:

70997d88c4 arm: rpi: Add a file to handle messages
The bcm283x chips provide a way for the ARM core to communicate with the
graphics processor, which is in charge of many things. This is handled by
way of a message prototcol.

At present the code for sending message (and receiving a reply) is spread
around U-Boot, primarily in the board file. This means that sending a
message from a driver requires duplicating the code.

Create a new message implementation with a function to support powering on
a subsystem as a starting point.
