In the regular\nboot sequence of:\n\nR5 SPL -> ATF -> OP-TEE -> A-core SPL -> U-Boot -> Kernel,\n\nBoth A-core SPL and U-Boot should be made aware of the memory reserved\nfor ATF and OP-TEE from their device-tree. Currently this information is\nabsent.\n\nTherefore this patch adds the reserved-memory regions as part of\nspl_perform_arch_fixups for the next stage's DT. This is called during\nboth R5 and A-core SPL which fixes up the DT for their respective next\nstages: A-core SPL and U-Boot proper.\n\nReviewed-by: Dhruva Gole <d-gole@ti.com>\nSigned-off-by: Anshul Dalal <anshuld@ti.com>\nTested-by: Wadim Egorov <w.egorov@phytec.de>\n---\n arch/arm/mach-k3/common.c | 11 +++++++++++\n 1 file changed, 11 insertions(+)", "diff": "diff --git a/arch/arm/mach-k3/common.c b/arch/arm/mach-k3/common.c\nindex 30ad98a68a2..f734f10b605 100644\n--- a/arch/arm/mach-k3/common.c\n+++ b/arch/arm/mach-k3/common.c\n@@ -321,6 +321,17 @@ static __maybe_unused void k3_dma_remove(void)\n \t\tpr_warn(\"DMA Device not found (err=%d)\\n\", rc);\n }\n \n+void spl_perform_arch_fixups(struct spl_image_info *spl_image)\n+{\n+\tvoid *fdt = spl_image_fdt_addr(spl_image);\n+\n+\tif (!fdt)\n+\t\treturn;\n+\n+\tfdt_fixup_reserved(fdt, \"tfa\", CONFIG_K3_ATF_LOAD_ADDR, 0x80000);\n+\tfdt_fixup_reserved(fdt, \"optee\", CONFIG_K3_OPTEE_LOAD_ADDR, 0x1800000);\n+}\n+\n void spl_board_prepare_for_boot(void)\n {\n #if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))\n", "prefixes": [ "v10", "09/11" ] }
