According to recently firmware handsoff spec [1]'s "Register usage at handoff
boundary", Transfer List's signature value was changed from 0x40_b10b
(3 bytes) to 4a0f_b10b (4 bytes).
As updating of TL's signature, register value of x1/r1 should be:
In aarch32's r1 value should be
R1[23:0]: set to the TL signature (4a0f_b10b -> masked range value: 0f_b10b)
R1[31:24]: version of the register convention == 1
and
In aarch64's x1 value should be
X1[31:0]: set to the TL signature (4a0f_b10b)
X1[39:32]: version of the register convention == 1
X1[63:40]: MBZ
(See the [2] and [3]).
This patch fix problems:
1. breaking X1 value with updated specification in aarch64
- change of length of signature field.
2. previous error value set in R1 in arm32.
- length of signature should be 24, but it uses 32bit signature.
This patch is a breaking change. It works only TF-A is updated.

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

During bloblist initialization, load the bloblist via boot arguments
from the previous loader.
If a valid bloblist exists in boot arguments, relocate it into the

If not, fallback to support BLOBLIST_ADDR or BLOBLIST_ALLOC.

Typically the bloblist is set up after the devicetree is present. This
makes sense because bloblist may use malloc() to allocate the space it
needs.
However sometimes the devicetree itself may be present in the bloblist.
In that case it is at a known location in memory so we can init the
bloblist very early, before devicetree.
Add a flag to indicate whether the bloblist has been inited. Add a
function to init it only if needed. Use that in the init sequence.

At present we do support allocating the bloblist but the Kconfig is a bit
strange, since we still have to specify an address in that case. Partly
this is because it is a pain to have CONFIG options that disappears when
its dependency is enabled. It means that we must have #ifdefs in the code,
either in the C code or header file.
Make use of IF_ENABLED_INT() and its friend to solve that problem, so we
can separate out the location of bloblist into a choice. Put the address
and size into variables so we can log the result.
Add the options for SPL as well, so we can use CONFIG_IS_ENABLED().

At present if someone adds a tag in the middle of the list it works well
enough within a U-Boot build. But if these tags are used in another
project, or with an older version of SPL, the numbers make become
inconsistent.
Use explicit tag numbers that never change, to resolve this problem.
Allocate areas for existing U-Boot tags and set up an area for use by
projects and vendors, as well as for private use. Keep tags above
0x10000 unallocated for now.

Typically the bloblist is positioned at a fixed address in memory until
relocation. This is convenient when it is set up in SPL or before
relocation.
But for EFI we want to set it up only when U-Boot proper is running. Add
a way to allocate it using malloc() and update the documentation to cover
this aspect of bloblist.
Note there are no tests of this feature at present, nor any direct testing
of bloblist_init().
This can be added, e.g. by making this option controllable at runtime.

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

At present there is no standard way in U-Boot to pass information from SPL
to U-Boot proper. But sometimes SPL wants to convey information to U-Boot
that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM
then it might want to pass the size of SDRAM, or the location of each
bank, to U-Boot proper.
Add a new 'bloblist' feature which provides this. A bloblist is set up in
the first phase of U-Boot that runs (i.e. TPL or SPL). The location of
this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else.
Information placed in this region is preserved (with a checksum) through
TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM
so it can be used after relocation.
