Hardware convenience library The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>
