CONFIG_UBC_WAKEUP: Wakeup UBC on startup

General informations

The Linux kernel configuration item CONFIG_UBC_WAKEUP:

prompt: Wakeup UBC on startup
type: tristate
depends on: CONFIG_CPU_SH4 && ! CONFIG_CPU_SH4A
defined in arch/sh/Kconfig
found in Linux Kernels: from 2.6.0 release to 2.6.32 release, thus this is an obsolete configuration

Help text

Selecting this option will wakeup the User Break Controller (UBC) on startup. Although the UBC is left in an awake state when the processor comes up, some boot loaders misbehave by putting the UBC to sleep in a power saving state, which causes issues with things like ptrace().

If unsure, say N.
