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not bother to keep the PPA support as it's long outdated and it would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

pbl-y doesn't exist as variable and is unused. What was meant here is
pblb-y and it should contain the name of the entry function.

if_changed should be used in conjunction with FORCE to make sure the
command is executed when the command line has changed.

The tqmls1046a also has a 8GiB DDR variant. This patch adds support for
this variant as an additional image with suffix _8g in the name.
The 8GiB boards use two different types of DDR chips which can be
distinguished by reading the EEPROM. There is one regular version which
has the string "TQMLS1046A-P2.0201" is the EEPROM. The other one is
possibly only used for Arkona and has the string "TQMLS1046A-CA.0202"
in the EEPROM. There might be other possible strings we are currently
not aware of, we fall back to the P2 variant in this case.

memsize is set with the value returned from fsl_ddr_sdram(), then passed
through r0 to the full barebox binary where it is then finally unused.
Just remove the variable. The real memory amount is hardcoded in the
board code anyway.

The various Layerscape xload_start_image functions all take r0, r1 and
r2 arguments. These are all unused in the code, so remove them.
The ls1021aiot board passes the memory size in r0 in one case, but this
is never used, so it's safe to remove that as well.

From: Sascha Hauer @ 2024-10-22 7:46 UTC (permalink / raw)
To: open list:BAREBOX
Right now we still use PPA on LS1046a. This has long been deprecated and
replaced with TF-A. Add support for starting the TF-A on LS1046a based
boards as a first step to get rid of PPA.

Now that we can start TF-A on LS1046a based boards switch the LS1046ardb
over to use this rather than deprecated PPA.
Unlike the PPA the TF-A needs information about the amount of SDRAM
installed on the board. The LS1046a-rdb has a DDR4 DIMM connector, so
the SDRAM configuration must be runtime detected. The board support has
8GiB hardcoded in other places, so hardcode 8GiB for TF-A as well.
