arm: Add support for CONFIG_ENABLE_DMM
Add a new config ENABLE_DMM that will turn on/off the DMM feature.
DMM stands for "dynamic memory management" (the ability to power
off some memory when the system is idle) and the reason this
is needed is that many customers do not want this functionality
and we want to provide a consistent and simple way of turning
this off, rather than the ad-hoc methods some have been using.
DMM currently is enabled by default on 8960.
The following configs are currently used only by DMM
and will be disabled if ENABLE_DMM is not true.
CONFIG_MEMORY_HOTPLUG
CONFIG_HOTREMOVE
CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG
CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE
CONFIG_MIGRATION
CONFIG_ARCH_MEMORY_PROBE
CONFIG_ARCH_MEMORY_REMOVE
