From 2058967d2fe8f93142d774bc47241d80894027d5 Mon Sep 17 00:00:00 2001 From: Hou Zhiqiang Date: Thu, 17 Feb 2022 11:51:36 +0800 Subject: [PATCH] tools: pblimage: fix image header verification function The Layerscape platforms have different RCW header value from FSL PowerPC platforms, the current image header verification callback is only working on PowerPC, it will fail on Layerscape, this patch is to fix this issue. This is a historical problem and exposed by the following patch: http://patchwork.ozlabs.org/project/uboot/patch/20220114173443.9877-1-pali@kernel.org Signed-off-by: Hou Zhiqiang Reviewed-by: Priyanka Jain --- Makefile | 2 +- tools/pblimage.c | 10 ++++++++-- tools/pblimage.h | 3 ++- 3 files changed, 11 insertions(+), 4 deletions(-) diff --git a/Makefile b/Makefile index 66d9e78cc7..4d9cda7f30 100644 --- a/Makefile +++ b/Makefile @@ -1411,7 +1411,7 @@ MKIMAGEFLAGS_u-boot-spl.kwb = -n $(KWD_CONFIG_FILE) \ $(if $(KEYDIR),-k $(KEYDIR)) MKIMAGEFLAGS_u-boot.pbl = -n $(srctree)/$(CONFIG_SYS_FSL_PBL_RCW:"%"=%) \ - -R $(srctree)/$(CONFIG_SYS_FSL_PBL_PBI:"%"=%) -T pblimage + -R $(srctree)/$(CONFIG_SYS_FSL_PBL_PBI:"%"=%) -A $(ARCH) -T pblimage ifeq ($(CONFIG_MPC85xx)$(CONFIG_OF_SEPARATE),yy) UBOOT_BIN := u-boot-with-dtb.bin diff --git a/tools/pblimage.c b/tools/pblimage.c index 3c823e96cf..bd639c276f 100644 --- a/tools/pblimage.c +++ b/tools/pblimage.c @@ -230,19 +230,25 @@ static int pblimage_verify_header(unsigned char *ptr, int image_size, struct image_tool_params *params) { struct pbl_header *pbl_hdr = (struct pbl_header *) ptr; + uint32_t rcwheader; + + if (params->arch == IH_ARCH_ARM) + rcwheader = RCW_ARM_HEADER; + else + rcwheader = RCW_PPC_HEADER; /* Only a few checks can be done: search for magic numbers */ if (ENDIANNESS == 'l') { if (pbl_hdr->preamble != reverse_byte(RCW_PREAMBLE)) return -FDT_ERR_BADSTRUCTURE; - if (pbl_hdr->rcwheader != reverse_byte(RCW_HEADER)) + if (pbl_hdr->rcwheader != reverse_byte(rcwheader)) return -FDT_ERR_BADSTRUCTURE; } else { if (pbl_hdr->preamble != RCW_PREAMBLE) return -FDT_ERR_BADSTRUCTURE; - if (pbl_hdr->rcwheader != RCW_HEADER) + if (pbl_hdr->rcwheader != rcwheader) return -FDT_ERR_BADSTRUCTURE; } return 0; diff --git a/tools/pblimage.h b/tools/pblimage.h index 81c5492926..0222e8067b 100644 --- a/tools/pblimage.h +++ b/tools/pblimage.h @@ -8,7 +8,8 @@ #define RCW_BYTES 64 #define RCW_PREAMBLE 0xaa55aa55 -#define RCW_HEADER 0x010e0100 +#define RCW_ARM_HEADER 0x01ee0100 +#define RCW_PPC_HEADER 0x010e0100 struct pbl_header { uint32_t preamble;
