[PATCH v2 0/6] elf: add better bootm support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, when booting an elf file using "bootm /dev/mtdx", bootm will
simply pass the file to the bootm and the read done on it will read the
entire flash partition. This series starts by some cleanup and then add an
elf_open function to load the elf file size only based on the elf header.
A special handling for the elf file is also added in bootm data to allow
using directly the elf file structure. Finally the mips bootm is modified
to use bootm elf loading capability.

Changes v1 -> v2
 - Add BOOTM_ELF config to select elf support and add checks in code
 - Add an elf_get_mem_size function to avoid computing elf size in bootm.c
 - Use xmalloc and read_full in elf_open instead of xzalloc/read
 - Fix data->elf NULL reset
 - Remove elf struct entirely from mips bootm code
