Message:

Move dynamic-linking related ELF definitions to ABI includes

Move dynamic-linking related ELF definitions from
uspace/lib/c/include/rtld/elf_dyn.h to abi/include/abi/elf.h. This
allows their use by the AArch64 boot code.

• abi/include/abi/elf.h (modified) (4 diffs)
• uspace/lib/c/include/rtld/elf_dyn.h (modified) (1 diff)
