H A D | arm64.c | d9ffe524a538720328b5bf98733a6c641e236bc8 Thu Oct 13 03:17:20 CDT 2022 Ard Biesheuvel <ardb@kernel.org> efi/arm64: libstub: Split off kernel image relocation for builtin stub
The arm64 build of the EFI stub is part of the core kernel image, and therefore accesses section markers directly when it needs to figure out the size of the various section.
The zboot decompressor does not have access to those symbols, but doesn't really need that either. So let's move handle_kernel_image() into a separate file (or rather, move everything else into a separate file) so that the zboot build does not pull in unused code that links to symbols that it does not define.
While at it, introduce a helper routine that the generic zboot loader will need to invoke after decompressing the image but before invoking it, to ensure that the I-side view of memory is consistent.
