[PATCH v2 00/12] ARM: Layerscape: LS1046a: switch to TF-A

[Sascha Hauer]

Our LS1046a support still uses the long deprecated and binary-only PPA
secure monitor firmware. It's time to switch this over to TF-A. We do
not bother to keep the PPA support as it's long outdated and it would
also make the code code and barebox configuration unnecessarily
complicated.

Changes in v2:
- add missing FORCE in images/Makefile.layerscape
- drop -16 cargo cult when setting up a stack
- use pr_debug rather than printf
- add TF-A firmware to test/generate-dummy-fw.sh
- drop ppA firmware from test/generate-dummy-fw.sh
- update documentation
- disable CAAM JR3 for the kernel, it's used by TF-A
- Link to v1: https://lore.barebox.org/20241021-arm-layerscape-tfa-v1-0-0980697b6f66@pengutronix.de
