common/spl: use memmove() in load_simple_fit()
I had trouble booting some am335x boards (both
beagleboneblack and a custom board). SPL would start just fine, and
apparently load U-Boot proper, but it would hang when jumping to
U-Boot.
While debugging, I stumbled on this memcpy() which from code
inspection very much looked to have overlapping src and dst, and
indeed a simple printf revealed
calling memcpy(0x8087bf68, 0x8087bf80, 0xf7f8)
Now, it will always be with src > dst, our memcpy()
implementations "most likely" do forward-copying, and in the end it
turned out that this wasn't the culprit after all [*].
But to avoid me or others barking up the wrong tree in the future, and
because this use of memcpy() is technically undefined, use memmove()
instead.

since been fixed in master but not the v2025.07 I worked of by 52caad0d14a ("ARM: Align image end to 8 bytes to fit DT alignment").

memtest: only call schedule() once for every 256 words
A function call itself for every word written or read+written in these
loops is bad enough. But since the memory test must be run with dcache
disabled, the schedule() call, traversing the linked list of
registered cyclic clients, and accessing the 'struct cyclic_info' for
each to see if any are due for a callback, is quite expensive. On a
beagleboneblack, testing a modest 16MiB region takes 2.5 minutes:
=> dcache off

Iteration: 1

There is really no need for calling schedule() so frequently. It is
quite easy to limit the calls to once for every 256 words by using a

during those ~4000 milliseconds, so the schedule() calls are still
done less than 0.1ms apart.
These numbers are just for a beagleboneblack, other boards may have a
slower memory, but we are _two orders of magnitude_ away from
schedule() "only" being called at 100Hz, which is still more than
enough to ensure any watchdog is kept happy.

memtest: don't volatile-qualify local variables
It is obviously important that the addr pointer used to access the
memory region being tested is volatile-qualified, to prevent the
compiler from optimizing out the "write this value, read it back,
check that it is what we expect".
However, none of these auxiliary variables have any such need for,
effectively, being forced to live on the stack and cause each and
every reference to them to do a memory access.
This makes the memtest about 15% faster on a beagleboneblack.

It turns out that all boards using the PCA9450 actually have the
SD_VSEL input connected to the VSELECT signal of the SoCs SD/MMC
interface. Therefore we don't need manual control for this signal
via GPIO and there aren't any users.
This is equivalent to the following change in Linux:

power: regulator: tps65910: Cannot test unsigned for being negative
The code in tps65910_regulator.c treats the field supply in struct
tps65910_regulator_pdata as an int and even tests the value for being
negative so change it from a u32 to int so that the code all works as
expected.
This issue was found by Smatch.

Merge patch series "power: regulator: Fix some Smatch reported issues"
Andrew Goodbody <andrew.goodbody@linaro.org> says:
Smatch reported some issues in the regulator drivers, mostly repeated
instances of testing an unsigned variable for being negative but also an
expression needing parenthesis to be interpreted as expected.

power: Split *POWER_LEGACY portion of <power/pmic.h> out to new header
The commends in include/power/pmic.h say that once SPL_DM_PMIC exists we
should update things. This has been true for some time, so let us update
this to have the legacy portions in their own header, which should not
be directly included. This cleans up the logic within the file too
slightly.
