mkimage: allow zynqmpbif to use a register initialization file

2026-07-08T06:55:51Z

The ZynqMP Boot Image Format allows specifying the register initialization file with the "[init]" attribute. Since this feature is already supported by the "zynqmpimage" backend, this commit leverages that existing capability to add support for the "[init]" attribute in the zynqmpbif backend: https://docs.amd.com/r/en-US/ug1283-bootgen-user-guide/init This currently uses the same register initialization file format as zynqmpimage (ASCII text hex values with each line composed of a pair of register address and value), for example: === 0xff003248 0x12345678 === It is not, yet, compatible with the format used by bootgen: https://docs.amd.com/r/en-US/ug1283-bootgen-user-guide/Initialization-Pairs-and-INT-File-Attribute Use this feature, with other zynqmpbif options, like so: === image : { [init] reginit.int [bootloader] fsbl.elf [pmufw_image] pmufw.elf [destination_cpu=a53-0, exception_level=el-3] bl31.elf [destination_cpu=a53-0, exception_level=el-2, load=0x08000000, startup=0x08000000] u-boot.bin } === Signed-off-by: Erich E.

tools: zynqmpbif: Use compiler builtin instead of linux-specific __swab32

2019-10-28T17:32:51Z

__swab32() is a Linux specific macro defined in linux/swab.h. Let's use the compiler equivalent builtin function __builtin_bswap32() for better portability. Signed-off-by: Bin Meng

tools: zynqmpimage: Align image_size/image_stored_size

2019-01-24T09:03:44Z

Bootrom is not capable to work with non aligned bootloader sizes. SPL with OF_SEPARATE generates non-align images quite often that's why this change is required before OF_SEPARATE enableding. Signed-off-by: Michal Simek

tools: zynqmpimage: round up partition size

2019-01-24T09:03:42Z

The FSBL copies "Total Partition Word Length" * 4 bytes from the boot.bin, which implies that the partition size is 4 byte aligned. When writing the partition, mkimage calculates "Total Partition Word Length" by dividing the size by 4. This implicitly cuts unaligned bytes at the end of the added binary. Instead of rounding down, the size must be round up to 4 bytes and the binary padded accordingly. Signed-off-by: Michael Tretter Reviewed-by: Alexander Graf Signed-off-by: Michal Simek

tools: zynqmpimage: Add bif support

2018-05-11T07:23:44Z

The officially described way to generate boot.bin files for ZynqMP is to describe the contents of the target binary using a file of the "bif" format. 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 Signed-off-by: Michal Simek
