We keep the check on /reserved-memory/optee@ node to have backward compatibility with STMT32Image booting, when the reserved node is already present in U-Boot or SPL device tree with name "optee@". This patch solves a boot issue on board with OP-TEE for U-Boot compiled with stm32mp15_defconfig and without secure configuration device tree (stm32mp157c-dk2.dts for example). Fixes: 5fe9e0deabb1 ("stm32mp: allow calling optee_get_reserved_memory() from U-Boot") Signed-off-by: Patrick Delaunay --- diff --git a/arch/arm/mach-stm32mp/dram_init.c b/arch/arm/mach-stm32mp/dram_init.c index a2ad6d1aaa..b06105768b 100644 --- a/arch/arm/mach-stm32mp/dram_init.c +++ b/arch/arm/mach-stm32mp/dram_init.c @@ -25,8 +25,11 @@ int optee_get_reserved_memory(u32 *start, u32 *size) ofnode node; node = ofnode_path("/reserved-memory/optee"); - if (!ofnode_valid(node)) - return -ENOENT; + if (!ofnode_valid(node)) { + node = ofnode_path("/reserved-memory/optee_core"); + if (!ofnode_valid(node)) + return -ENOENT; + } fdt_start = ofnode_get_addr_size(node, "reg", &fdt_mem_size); *start = fdt_start;
