From 1ad2134f914dfd4c8f92307c94c9a5a1e28f0059 Mon Sep 17 00:00:00 2001 From: Paul Brook Date: Tue, 19 May 2009 16:17:58 +0100 Subject: 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.
