Make include/common.h usable by assembler code
Commit 70ebf316 factored out the ROUND() macro into include/common.h, not realizing that the primary use of this macro on AT91 systems was in start.S where common.h was not included, and could not be included because it contains a lot of C code which the assembler doesn't understand. This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__" construct, and then adds an include to cpu/arm926ejs/start.S thus solving the problem. Signed-off-by: Wolfgang Denk <wd@denx.de>
