* mn10300: add cc clobbers to asm statementsMark Salter2010-01-113-4/+6
| | | | | | | | | | | | | gcc 4.2.1 for MN10300 is more agressive than the older gcc in reordering/moving other insns between an insn that sets flags and an insn that uses those flags. This leads to trouble with asm statements which are missing an explicit "cc" clobber. This patch adds the explicit "cc" clobber to asm statements which do indeed clobber the condition flags.

* mn10300: add the MN10300/AM33 architecture to the kernelDavid Howells2008-02-0816-0/+1299
Add architecture support for the MN10300/AM33 CPUs produced by MEI to the kernel. This patch also adds board support for the ASB2303 with the ASB2308 daughter board, and the ASB2305. The only processor supported is the MN103E010, which is an AM33v2 core plus on-chip devices.
