bsp_delay.... Question

Some BSPs have a bsp_delay method.  This is
a short duration spinner.  We think it is in
microsecond units but have no idea for sure
and it could vary by BSP.

Jennifer and I would like to formalize the
definition of this.  And standardize it across
BSPs.  So if it is available, it is safer to
use. Questions are

+ OK to make a standard BSP method?
+ Microseconds unit?

If it is not available, what should the stub do?

Should we have bsp_delay_usecs() and bsp_delay_nsecs?

Comments appreciated!  Please
