The requirement that .dtbos have load addresses in the FIT image
vanished five years ago with

  4c531d9f58b ("fit: Load DTO into temporary buffer and ignore load address")

Fix the documentation accordingly.

<title>treewide: fix uImage.FIT document paths</title>

Commit 488445cefa1 ("doc: Move FIT into its own directory") moved the
documentation in doc/uImage.FIT to doc/usage/fit, subsequently all
documents and example sources have been converted to reStructuredText.

Fix (almost) all of the remaining occurrences of the old path and
filenames across the tree.

The exception is doc/uImage.FIT/command_syntax_extensions.txt which
apparently has been removed entirely, or at least I was unable to
locate where that document is now.

<title>boot: Add fit_config_get_hash_list() to build signed node list</title>

<content type='text'>
The hashed-nodes property in a FIT signature node lists which FDT paths
are included in the signature hash. It is intended as a hint so should
not be used for verification.

Add a function to build the node list from scratch by iterating the
configuration's image references. Skip properties known not to be image
references. For each image, collect the path plus all hash and cipher
subnodes.

Use the new function in fit_config_check_sig() instead of reading
'hashed-nodes'.

Update the test_vboot kernel@ test case: fit_check_sign now catches the
attack at signature-verification time (the @-suffixed node is hashed
instead of the real one, causing a mismatch) rather than at
fit_check_format() time.

Update the docs to cover this. The FIT spec can be updated separately.

<title>ARM: bootm: Add support for starting Linux through OPTEE-OS on ARMv7a</title>

<id>20861863eb3010581b12e9a77eb7958460edaa82</id>
<content type='text'>
Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a.
This is only supported if U-Boot runs in PL1 secure. This change adds
two components, one is fitImage OPTEE-OS loadable handler, which makes
a note of OPTEE-OS being loaded and stores the load address for later
jump to it. The second part is the actual jump to Linux through OPTEE-OS.
The jump through OPTEE-OS requires set up of multiple CPU registers, r1
and r2 are passed through, r0 and r3 have to be set to 0, lr is set to
Linux kernel entry point. This setup is done by new assembler function
boot_jump_linux_via_optee().

The boot_jump_linux_via_optee() also includes STM32MP13xx late TZC
configuration write, this cannot be moved easily, hence the ifdef.
