At present the simple FIT-loader always loads images, ignoring whether
they are intended for the next phase or not.
VBE packages up several images in the same FIT, some destined for VPL
and some for SPL. Add logic to check the phase before loading the
image. Return -EPERM in that case and handle it gracefully.

This includes various patches towards implementing the VBE abrec
bootmeth in U-Boot. It mostly focuses on introducing a relocating
SPL-loader so that VBE can run in the limited amount of SRAM available
on many devices.
Another minor new feature is support in VBE for specifying the image
phase when loading from a FIT. This allows a single FIT to include
images for several boot phases, thus simplifying image-creation.
One lingering niggle in this series is that it has a different code path
for sandbox, since it does not support the relocating jump. It should be
possible to resolve this with additional work, but I have not attempted
this so far.
For v2, I have split the first patch into 5 pieces, to make it easier to
see the code-size impact, plus added a few tweaks to reduce code size.
Again, only MMC is supported so far.
Looking ahead, series G will have some more plumbing and H some rk3399
pieces. That should be enough to complete these feature.
Here is a run in my lab, with the VBE ABrec bootmeth. You can see that
VPL runs before memory is set up. SPL sets up memory and can be upgraded
in the field reliably.

This is fairly easy to use. The SPL loader sets up some fields in the
spl_image_info struct and calls spl_reloc_prepare(). When SPL is ready
to do the jump it must call spl_reloc_jump() instead of jump_to_image().
Add this logic.

When one xPL phase wants to jump to the next, the next phase must be
loaded into its required address. This means that the TEXT_BASE for the
two phases must be different and there cannot be any memory overlap
between the code used by the two phases. It also can mean that phases
need to be moved around to accommodate any size growth.
Having two xPL phases in SRAM at the same time can be tricky if SRAM
is limited, which it often is. It would be better if the second phase
could be loaded somewhere else, then decompressed into place over the
top of the first phase.
Introduce a relocating jump for xPL to support this. This selects a
suitable place to load the (typically compressed) next phase, copies
some decompression code out of the first phase, then jumps to this code
to decompress and start the next phase.
This feature makes it much easier to support Verified Boot for Embedded
(VBE) on RK3399 boards, which have 192KB of SRAM.

On 32 bits platforms, timer_get_us() returns an unsigned long which
is a 32 bits. timer_get_us() wraps around every 72 minutes
(2 ^ 32 / 1000000 =~ 4295 sec =~ 72 min).
So the test "if time_after_eq64(now, cyclic->next_call)" is no more
true when cyclic->next_call becomes above 32 bits max value (4294967295).
At this point after 72 min, no more cyclic function are
executed included watchdog one.
Instead of using timer_get_us(), use get_timer_us() which returns a
uint64_t, this allows a rollover every 584942 years.

Rather than doing autoprobe within the driver model code, move it out to
the board-init code. This makes it clear that it is a separate step from
binding devices.
For now this is always done twice, before and after relocation, but we
should discuss whether it might be possible to drop the post-relocation
probe.
For boards with SPL, the autoprobe is still done there as well.
Note that with this change, autoprobe happens after the
EVT_DM_POST_INIT_R/F events are sent, rather than before.

Introduce CONFIG_SPL_64BIT and select it for architectures other than
x86 with 64 bit builds. Do not select it for x86 builds as x86 uses
a 32 bit SPL.
Ensure that when limits are set they use CONFIG_64BIT for U-Boot
proper and CONFIG_SPL_64BIT for SPL. This is to allow for the 32 bit
SPL build used by x86.
