First patch modifies the type of len argument (in da_to_va) in order to allow loading elf64 segment with a u64 size. Second patch is the actual modification in the elf loader to support elf64 type by using a set of generic macros. Changes from V2: - da_to_va len type changed from int to u64 - Add check for elf64 header size - Add comments for name table parsing - Fix typo in "accommodate" Clement Leger (2): remoteproc: Use u64 len for da_to_va remoteproc: Add elf64 support in elf loader Documentation/remoteproc.txt | 2 +- drivers/remoteproc/imx_rproc.c | 9 +- drivers/remoteproc/keystone_remoteproc.c | 2 +- drivers/remoteproc/qcom_q6v5_adsp.c | 2 +- drivers/remoteproc/qcom_q6v5_mss.c | 2 +- drivers/remoteproc/qcom_q6v5_pas.c | 2 +- drivers/remoteproc/qcom_q6v5_wcss.c | 2 +- drivers/remoteproc/qcom_wcnss.c | 2 +- drivers/remoteproc/remoteproc_core.c | 2 +- drivers/remoteproc/remoteproc_elf_loader.c | 147 ++++++++++++++++++----------- drivers/remoteproc/remoteproc_elf_loader.h | 69 ++++++++++++++ drivers/remoteproc/remoteproc_internal.h | 4 +- drivers/remoteproc/st_remoteproc.c | 2 +- drivers/remoteproc/st_slim_rproc.c | 4 +- drivers/remoteproc/wkup_m3_rproc.c | 2 +- include/linux/remoteproc.h | 6 +- 16 files changed, 184 insertions(+), 75 deletions(-) create mode 100644 drivers/remoteproc/remoteproc_elf_loader.h
