As part of bringing the master branch back in to next, we need to allow

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

A follow-up to commit 842fb5de424e
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6f7
("drivers: use devfdt_get_addr_index_ptr when cast to pointer").
In addition to using the *_ptr variants of these functions where the
address is cast to a pointer, this also changes devfdt_get_addr_*() to
dev_read_addr_*() in a few places. Some variable and field types are
changed from fdt_addr_t or phys_addr_t to void* where the cast was
happening later.
This patch fixes a number of compile warnings when building a 32bit
U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error
handling where the return value of dev_read_addr() etc. was checked for
NULL instead of FDT_ADDR_T_NONE.

Sec proxy data buffer is 60 bytes with the last of the registers
indicating transmission completion. This however poses a bit of a
challenge.
The backing memory for sec_proxy is regular memory, and all sec proxy
does is to trigger a burst of all 60 bytes of data over to the target
thread backing ring accelerator. It doesn't do a memory scrub when
it moves data out in the burst. When we transmit multiple messages,
remnants of previous message is also transmitted which results in
some random data being set in TISCI fields of messages that have been
expanded forward.
The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.
So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).
This allows us to scale and introduce ABI changes back also work with
other boot stages that may have left data in the internal memory.
While at this, drop the unused accessor function.

AM64x uses a different thread mapping that existing K3 SoCs, so update
the valid thread ID list to include those used for AM64x.
Also remove the comment identifying the purpose of each thread ID. The
purpose of the thread ID is specified when describing the threads in the
device tree and the same ID can mean different things on different SoCs,
so the comment is not useful.

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.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

This function name conflicts with our desire to #define free() to
something else on sandbox. Since it deals with resources, rename it to
