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 It's time to switch this over to TF-A. We do not bother to keep the PPA support as it's long outdated and it would also make the code code and barebox configuration unnecessarily complicated. Signed-off-by: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx> --- 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@xxxxxxxxxxxxxx --- Sascha Hauer (12): ARM: Layerscape: TQMLS1046a: Update DDR timings ARM: Layerscape: images: fix variable name ARM: Layerscape: images: add missing FORCE ARM: Layerscape: TQMLS1046a: add support for 8GiB variant ARM: Layerscape: ls1046ardb: remove unused variable ARM: Layerscape: remove register arguments ARM: Layerscape: LS1046a: add TF-A support ARM: Layerscape: LS1046a-rdb: Switch to TF-A support ARM: Layerscape: TQMLS1046a: Switch to TF-A support ARM: Layerscape: LS1046a: remove PPA support ARM: Layerscape: LS1046a: add PSCI node ARM: Layerscape: Update Documentation for TF-A Documentation/boards/layerscape.rst | 13 +- arch/arm/boards/ls1021aiot/lowlevel.c | 6 +- arch/arm/boards/ls1046ardb/board.c | 6 - arch/arm/boards/ls1046ardb/lowlevel.c | 29 ++- arch/arm/boards/ls1046ardb/start.S | 14 +- arch/arm/boards/tqmls1046a/board.c | 37 +++- arch/arm/boards/tqmls1046a/lowlevel.c | 327 ++++++++++++++++++++++++++++++---- arch/arm/boards/tqmls1046a/start.S | 19 +- arch/arm/dts/fsl-ls1046a.dtsi | 5 + arch/arm/mach-layerscape/Kconfig | 14 +- arch/arm/mach-layerscape/Makefile | 2 +- arch/arm/mach-layerscape/ppa-entry.S | 32 ---- arch/arm/mach-layerscape/ppa.c | 147 --------------- arch/arm/mach-layerscape/soc.c | 32 ++++ arch/arm/mach-layerscape/tfa.c | 32 ++++ arch/arm/mach-layerscape/xload-qspi.c | 19 +- arch/arm/mach-layerscape/xload.c | 12 +- drivers/mci/imx-esdhc-pbl.c | 13 +- firmware/Kconfig | 3 + firmware/Makefile | 2 +- images/Makefile.layerscape | 36 ++-- include/mach/layerscape/layerscape.h | 11 +- include/mach/layerscape/xload.h | 16 +- test/generate-dummy-fw.sh | 2 +- 24 files changed, 516 insertions(+), 313 deletions(-) --- base-commit: dda64a15ea026c95ccd8bd8a8b70c7e070af1a15 change-id: 20241021-arm-layerscape-tfa-74bb4fe5713e Best regards, -- Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>
