commit 7be0d19c751b02db778ca95e3274d5ea7f31891c upstream.
Selecting CONFIG_SAMSUNG_PM_DEBUG (depending on CONFIG_DEBUG_LL) but
without CONFIG_MMU leads to build errors:
arch/arm/plat-samsung/pm-debug.c: In function ‘s3c_pm_uart_base’:
arch/arm/plat-samsung/pm-debug.c:57:2: error:
implicit declaration of function ‘debug_ll_addr’
[-Werror=implicit-function-declaration]
Fixes: 99b2fc2b8b40 ("ARM: SAMSUNG: Use debug_ll_addr() to get UART base
address")

Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
