When we build the convenience firmware package file for the Arm FPGA boards (bl31.axf), we combine trampolines, the DTB and the actual BL31 code into one ELF file, which is more a "container with load addresses" than an actual executable. So far ld was fine with us using bl31.elf as an input file, but binutils 2.35 changed that and complains about taking an *executable* ELF file as in *input* to the linker: ----------------- aarch64-none-elf-ld.bfd: cannot use executable file 'build/arm_fpga/debug/./bl31/bl31.elf' as input to a link ----------------- Fortunately we don't need the actual BL31 ELF file for *that* part of the linking, so can use the just created bl31.bin binary version of it. Actually that shrinks the file, as we needlessly included the .BSS section in the final file before. Using the binary works with both older and newer toolchains versions, so let's do this unconditionally.
