401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

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.

fff5d5499d rpi4: Update memory map to accommodate scb devices
Some of the devices(for instance, pcie and gnet controller) sitting on
SCB bus falls behind/below the memory range that we currenty have.

This patch updates the memory range to map those devices correctly.

9edefc2776 common: Move some cache and MMU functions out of common.h
These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.

Move them over.

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.

cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier

ddf6bd4876 ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283x
BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2)
are similar enough.  One of the biggest differences is the ARM
processor.  It is reasonable to collect the source files into a
single place, arch/arm/mach-bcm283x/.
