Add a feature which speeds up the CPU to full speed in SPL to minimise boot time. This is only supported for certain boards (at present only jerry). Signed-off-by: Simon Glass <sjg@chromium.org>

help

Some boards want to boot as fast as possible. We can increase the
|
|
CPU frequency in SPL if the power supply is configured to the correct
|
|
voltage. This option is only available on boards which support it
|
|
and have the required PMIC code.
