CONFIG_MMC_DEBUG was introduced long time ago and mostly it's a all-or-none proposition for compile-time. By looking at how the mmc core use it, it's obviously pointless to still carry on this option. But referring to the host drivers, it's hard to say should we remove it now. The following drivers[1] will print some extra log on irq context for debugging. Probably folks still need to debug it sometimes but making it default behaviour seems to introduce some unnecessary burden for their drivers I guess. Anyway, we downgrade this option for hosts only and ask the following added host drivers to use this for debugging instead of adding their private macro to activate their debug functions. This patchset also cleanup wbsd and sdhci as it doesn't seem sensible to use CONFIG_MMC_DEBUG for their cases.
