-Subject: [PATCH 29/50] OMAP3: convert setup_auxcr() to pure asm
-
-This function consists entirely of inline asm statements, so writing
-it directly in a .S file is simpler. Additionally, the inline asm is
-not safe as is, since registers are not guaranteed to be preserved
-between asm() statements.
