Subject[PATCH] plugsched - update Kconfig
Date
Hi Peter et al

I find the Kconfig menu layout a little confusing and suggest the following
patch.

Cheers,
Con
Update the Kconfig menu for plugsched

Make the default cpu scheduler choice depend on the presence of that scheduler
being configured in rather than selecting it since the default is for all to
be built in unless manually deselected in the embedded menu.

Make a submenu for spa schedulers instead of having a flat list.
