This patch adds a save and restore mechanism for ARM L2 auxiliary control register. The feature is enabled by default for GP devices, but for HS/EMU devices the user must enable the service and define the PPA service ID to be used for setting L2 aux ctrl, as this is not currently supported by the bootloader. If nobody alters the contents of L2 aux ctrl from its reset value, this feature is not needed. Kconfig option to enable HS/EMU L2 aux save and restore: - OMAP3_L2_AUX_SECURE_SAVE_RESTORE Kconfig option to select HS/EMU PPA service for setting L2 aux ctrl: - OMAP3_L2_AUX_SECURE_SERVICE_SET_ID Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Say Y if you want to reset unused clocks during boot.
|
|
This option saves power, but assumes all drivers are
|
|
using the clock framework. Broken drivers that do not
|
|
yet use clock framework may not work with this option.
|
|
If you are booting from another operating system, you
|
|
probably do not want this option enabled until your

|
device drivers work properly.
