This file then links to other files that all get packed into a bootable image. This patch adds support to read such a .bif file and generate a respective ZynqMP boot.bin file that can include the normal image and pmu files, but also supports image partitions now. This makes it a handy replacement for the proprietary "bootgen" utility that is currently used to generate boot.bin files with FSBL. Signed-off-by: Alexander Graf --- v2 -> v3: - zero initialize header - reduce default debug verbosity v3 -> v4: - add error handling - add fsbl_config support - add aarch32 support - allow a5x to be written as a53 - add offset support - add support for partition_owner - ensure pmufw comes before bootloader - simplify fsbl_config - add non-a53 boot support - checkpatch fixes --- common/image.c | 1 + include/image.h | 1 + tools/Makefile | 1 + tools/imagetool.h | 1 + tools/mkimage.c | 7 + tools/zynqmpbif.c | 1008 +++++++++++++++++++++++++++++++++++++++++++++++++++ tools/zynqmpimage.c | 4 +- tools/zynqmpimage.h | 7 + 8 files changed, 1028 insertions(+), 2 deletions(-) create mode 100644 tools/zynqmpbif.c diff --git a/common/image.c b/common/image.c index e1c50eb25d..f30dfa229b 100644 --- a/common/image.c +++ b/common/image.c @@ -159,6 +159,7 @@ static const table_entry_t uimage_type[] = { { IH_TYPE_VYBRIDIMAGE, "vybridimage", "Vybrid Boot Image", }, { IH_TYPE_ZYNQIMAGE, "zynqimage", "Xilinx Zynq Boot Image" }, { IH_TYPE_ZYNQMPIMAGE, "zynqmpimage", "Xilinx ZynqMP Boot Image" }, + { IH_TYPE_ZYNQMPBIF, "zynqmpbif", "Xilinx ZynqMP Boot Image (bif)" }, { IH_TYPE_FPGA, "fpga", "FPGA Image" }, { IH_TYPE_TEE, "tee", "Trusted Execution Environment Image",}, { IH_TYPE_FIRMWARE_IVT, "firmware_ivt", "Firmware with HABv4 IVT" }, diff --git a/include/image.h b/include/image.h index a579c5f509..c5af912aeb 100644 --- a/include/image.h +++ b/include/image.h @@ -269,6 +269,7 @@ enum { IH_TYPE_RKSPI, /* Rockchip SPI image */ IH_TYPE_ZYNQIMAGE, /* Xilinx Zynq Boot Image */ IH_TYPE_ZYNQMPIMAGE, /* Xilinx ZynqMP Boot Image */ + IH_TYPE_ZYNQMPBIF, /* Xilinx ZynqMP Boot Image (bif) */ IH_TYPE_FPGA, /* FPGA Image */ IH_TYPE_VYBRIDIMAGE, /* VYBRID .vyb Image */ IH_TYPE_TEE, /* Trusted Execution Environment OS Image */ diff --git a/tools/Makefile b/tools/Makefile index 8143c25666..204685ec9e 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -113,6 +113,7 @@ dumpimage-mkimage-objs := aisimage.o \ ublimage.o \ zynqimage.o \ zynqmpimage.o \ + zynqmpbif.o \ $(LIBFDT_OBJS) \ gpimage.o \ gpimage-common.o \ diff --git a/tools/imagetool.h b/tools/imagetool.h index e67de9b5ad..6a7e7386f7 100644 --- a/tools/imagetool.h +++ b/tools/imagetool.h @@ -232,6 +232,7 @@ time_t imagetool_get_source_date( void pbl_load_uboot(int fd, struct image_tool_params *mparams);
