From: David Gibson Date: Fri, 11 Nov 2005 05:42:12 +0000 (+1100) Subject: [PATCH] powerpc: Move udbg code to arch/powerpc X-Git-Tag: v2.6.15-rc1~14^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=35cd8785de39c90a52287d0f041cff8a792eaa74;p=platform%2Fkernel%2Flinux-stable.git [PATCH] powerpc: Move udbg code to arch/powerpc Since the udbg code in ppc64 has no ppc32 equivalent, move it straight over into arch/powerpc (and include/asm-powerpc for udbg.h). In time, we probably want to meld the various bits and pieces of 32-bit early debugging code into udbg, but for now only include it on CONFIG_PPC64=y builds. The only change during the move is to standardise the protecting #ifdef/#define in udbg.h, and move its banner comment above the initial #ifdef (which seems to be normal practice). Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64). Built for 32bit multiplatform (ARCH=powerpc).
