[v5,0/8] remoteproc: Add elf64 support

Message

Clément Leger March 2, 2020, 9:38 a.m. UTC

This serie add support for elf64 in remoteproc (elf loader, coredump). 
First three patches modifies the type of len argument (in da_to_va),
boot_addr and rproc_mem_entry len field in order to allow loading elf64
segment with a u64 size and a u64 entry point.
Next patches introduce a set of macros to access elf64 and elf32
transparently.
Last patches are the actual modifications in the elf loader and
remoteproc coredump support to add elf64 support.

Changes v4 -> v5:
 - Add rproc_elf_sanity_check renaming to rproc_elf32_sanity_check
 - Fix checkpatch warning on > 80 column line
 - Change u64 len type for size_t in da_to_va and add checks in loader
 - Modify rproc_mem_entry size field type from int to size_t
 - Add a patch to override sanity_check function

Changes v3 -> v4:
 - Adapt coredump to elf64 file format
 - Rename remoteproc_elf_loader.h to remoteproc_elf_helpers.h
 - Update copyright year in remoteproc_elf_helpers.h
 - Rename macros elf_hdr_* to elf_get_hdr_* for coherency with elf_hdr_set_*
 - Split elf64 loader patch in 3:
   - boot_addr u64 change
   - remoteproc_elf_helpers.h creation
   - elf64 loading

Changes v2 -> v3:
 - 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
 - Add ELF64 support in documentation

Clement Leger (8):
  remoteproc: Use size_t type for len in da_to_va
  remoteproc: Use size_t instead of int for rproc_mem_entry len
  remoteproc: Use u64 type for boot_addr
  remoteproc: Add elf helpers to access elf64 and elf32 fields
  remoteproc: Rename rproc_elf_sanity_check for elf32
  remoteproc: Add elf64 support in elf loader
  remoteproc: Allow overriding only sanity_check
  remoteproc: Adapt coredump to generate correct elf type
