|
* clocking using the settings in board.h.

/* Don't change the current basic clock configuration if we are running
|
|
* from SDRAM. In this case, some bootloader logic has already configured
|
|
* clocking and SDRAM. We are pretty much committed to using things the
|
|
* way that the bootloader has left them.
|
|
*
|
|
* Clocking will be configured at 792 MHz initially when started via
|
|
* U-Boot. The Linux kernel will uses the CPU frequency scaling code
|
|
* which will switch the processor frequency between 400 MHz and 1GHz based
|
|
* on load and temperature. For now, NuttX simply leaves the clocking at
|
|
* 792MHz.
