Drystone provides a convenient sanity check that the CPU is running at full speed. Add this as a command which can be enabled as needed. Note: I investigated using Coremark for this but there was a license agreement and I could not work out if it was GPL-compatible. Signed-off-by: Simon Glass <sjg@chromium.org>

Dhrystone is an old benchmark in the public domain that gives a
|
|
rough idea of CPU performance. This enables a 'dhry' command
|
|
which runs this benchmark within U-Boot and reports the performance.
|
|
The number of 'Dhrystone MIPS' is also reported.
