Add a simple driver for the clocks provided by the MIPS Boston development board. The system provides information about 2 clocks whose rates are fixed by the bitfile flashed in the boards FPGA, and this driver simply reads the rates of these 2 clocks.

This allows drivers to be provided for clock generators, including
|
|
oscillators and PLLs. Devices can use a common clock API to request
|
|
a particular clock rate and check on available clocks. Clocks can
|
|
feed into other clocks in a tree structure, with multiplexers to
|
|
choose the source for each clock.

help

The clock subsystem adds a small amount of overhead to the image.
|
|
If this is acceptable and you have a need to use clock drivers in
|
|
SPL, enable this option. It might provide a cleaner interface to
|
|
setting up clocks within SPL, and allows the same drivers to be
|
|
used as U-Boot proper.
