There are three instances of coreboot.c in libpayload. for x86, arm and arm64 architectures. The arm and arm64 instances are exactly the same. The differences with the x86 instance are as follows: - a very slightly different set of coreboot table tags is parsed (one tag added and two removed) - instead of checking a fixed address if it contains the coreboot table, the x86 version iterates over two address ranges. This patch refactors the module, leaving architecture specific processing in arch subdirectories and moving the common code into libc.
