[PATCH] m68knommu: new family (523x) and board config support
New architecture and board configuration support for m68knommu. . add 523x ColdFire support . add support for SOM5282 and MOD5272 boards . break up the 527x to be separate 5271 and 5275. There is some subtle differences that (like RAM config) that need to be dealt with . add option to support selecting 4k kernel stack Signed-off-by: Greg Ungerer <gerg@uclinux.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
