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_load_os directly instead of manual elf loading. Changes v2 -> v3 - Integrate elf loading in bootm_load_os - Add patch to remove now unused elf_load_image/elf_release_image - Use malloc instead of xmalloc and check return value 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 Clement Leger (7): common: elf: add computation of elf boundaries common: elf: fix warning on 32 bits architectures common: elf: split init to be reused from other function common: elf: add elf_open, elf_close and elf_load common: bootm: add support for elf file loading mips: lib: bootm: use bootm elf loading capabilities common: elf: remove elf_load_image/elf_release_image arch/mips/lib/bootm.c | 31 +++++------- common/Kconfig | 8 ++++ common/bootm.c | 33 +++++++++++++ common/elf.c | 107 ++++++++++++++++++++++++++++++++++++------ include/bootm.h | 3 ++ include/elf.h | 16 ++++++- 6 files changed, 161 insertions(+), 37 deletions(-) -- 2.17.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
