AM64X hereby receives support for reset reason printing during boot.
Unfortunately does the AM64X register mapping slighlty differ from
the AM62X. WDT and PORZ are not part of the reset source register, but
the mapping remains the same for all other causes.
To prevent ifdef/else constructs, I decided to follow a simple
copy/paste approach and adjusted the logic accordingly.

Implement get_reset_reason() for AM64x to enable reporting of the reset
cause in the cpuinfo output.
Notice that the AM64x does not support dedicated reset cause bits for
WDT and PORZ as the AM62x does.
An explanation of this difference is not part of the technical reference
manual and remains unclear.

AM64X SoCs use similar but not identical bit mappings like the AM62X
family.
In detail does the AM64X not support PORZ and WDT as reset caused.
Add the mapping according to the technical reference manual into the
SoC specific header.

Make the fdt_map parameter a pointer to const, since the function only
reads the mapping table. This improves API correctness and allows maps
to live in read-only data.

Unlike other K3 SoC's, am65 SoC has the capability to detect daughter
cards and automatically generate a list of white-space separated overlays
in name_overlays environment variable.
When applied during boot with get_overlay_mmc, the path to overlays with
default distribution is incorrect where path is currently: boot/dtb and
the overlays exist in boot/dtb/ti.
Fix the path in get_overlay_mmc so that overlays are automatically applied
correctly during boot time.

Currently logic in spl_mmc_boot_mode only lookes at main devstat
to determine the bootmode to return. Thus, when using: 'eMMC boot'
as primary boot mode and 'MMCSD boot from eMMC UDA' as backup
boot mode, 'eMMC boot' is always selected. Add check for bootindex
to determine if ROM boot via backup boot mode and return MMCSD_MODE_FS
which is the only supported backup bootmode with eMMC device.

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.
[*] That was 358d1cc232 ("spl: Align FDT load address"), which has
since been fixed in master but not the v2025.07 I worked of by
52caad0d14 ("ARM: Align image end to 8 bytes to fit DT alignment").
