Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and local #defines into globally configurable kconfig options (and Options.lb options for as long as newconfig still exists) which can be enabled by the user in the "Debugging" menu. The respective menu items only appear if a board is selected where the chipset code actually provides such additional DEBUG output. All three variables default to 0 / off for now. Also, drop a small chunk of dead/useless code in the src/northbridge/via/cn700/raminit.c file, which would otherwise break compilation. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Reworked to still apply to trunk, added X86EMU_DEBUG (and make the x86emu/yabel code only work printf instead of a redefined version of printk and Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5185 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
