Zoom2/Zoom3 kind of boards do not use omap uarts for console. These use external debug board for console. So these boards should not have "Uncompressing Kernel...." log put on omap uarts. By interoducing OMAP_LL_DEBUG_NONE option, unnecessary writes to omap uarts is avoided. In future, the DEBUG_LL interface will be enhanced to use external debug board.

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.
