b6e83826ef bloblist: Reduce blob-header size
The v0.9 spec provides for an 8-byte header for each blob, with fewer
fields.
The blob data start address should be aligned to the alignment specified
by the bloblist header.
Update the implementation to match this.

997dac6ede bloblist: Checksum the entire bloblist
Use a sinple 8-bit checksum for bloblist, as specified by the spec
version 0.9.
Spec v0.9 specifies that the entire bloblist area is checksummed,
including unused portions. Update the code to follow this.

1a2e02f955 bloblist: Adjust API to align in powers of 2
The updated bloblist structure stores the alignment as a power-of-two
value in its structures. Adjust the API to use this, to avoid needing to
calling ilog2().
Update the bloblist alignment from 16 bytes to 8 bytes.
Drop a stale comment while we are here.

e748e4b780 bloblist: Update the tag numbering
Align bloblist tags with the FW handoff spec v0.9.
The most common ones are from 0.
TF related ones are from 0x100.
All non-standard ones from 0xfff000.

Added new defined tags:
BLOBLISTT_OPTEE_PAGABLE_PART for TF.
BLOBLISTT_TPM_EVLOG and BLOBLISTT_TPM_CRB_BASE for TPM.

f16ec77784 bloblist: Use explicit numbering for the tags
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.

Update bloblist_tag_name() and the tests to work with this new setup.

ff3bd4983c bloblist: Put the magic number first
It seems best to put the magic number right at the start of the bloblist
header, so it is easier to check. This is how devicetree works.

Make this change now, before other projects make use of bloblist. Other
changes may be needed / discussed, but that is TBD.

Add a checker function as well.

401d1c4f5d common: Drop asm/global_data.h from common header
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.

9fe064646d bloblist: Support relocating to a larger space
Typically in TPL/SPL the bloblist is quite small. But U-Boot proper may
want to add a lot more to it, such as ACPI tables.

Add a way to expand the bloblist by relocating it in U-Boot proper, along
with the other relocation activities.

4aed227623 bloblist: Add a command
It is helpful to be able to see basic statistics about the bloblist and
also to list its contents. Add a 'bloblist' command to handle this.

Put the display functions in the bloblist modules rather than in the
command code itself. That allows showing a list from SPL, where commands
are not available.

Also make bloblist_first/next_blob() static as they are not used outside
this file.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

4ad4edfe77 cmd_ut: add a parameter prefix to the function cmd_ut_category
There is black magic in the file conftest.py that list
all the test unit. Then, all those test unit are called
in pytest. This call is done with the end of the name
(for example checksum if the full name is bloblist_test_checksum).

The result is that only test for dm are really executed.
by pytest, all others tests are listed but never executed.

This behaviour happens because the dm test unit only check
the end of the name and others tests checks the full name.

To fix this issue, I've added a prefix to the function
cmd_ut_category, and this prefix is removed when looking
for the unit test.
