Igor Opaniuk c0f037f6a2 mach-imx: bootaux: elf firmware support ... Currently imx-specific bootaux command doesn't support ELF format firmware for Cortex-M4 core. This patches introduces a PoC implementation of handling elf firmware (load_elf_image_phdr() was copy-pasted from elf.c just for PoC). ELF64 binaries isn't supported yet. This has the advantage that the user does not need to know to which address the binary has been linked to. However, in order to handle and load the elf sections to the right address, we need to translate the Cortex-M4 core memory addresses to primary/host CPU memory addresses (Cortex A7/A9 cores). This allows to boot firmwares from any location with just using bootaux, e.g.: > tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr} Similar translation table can be found in the Linux remoteproc driver [1].
