But there are still no timer interrupts. LEDs do not appear to be working.
2016-05-17: Timer interrupts now work. This turned out to be just a minor
bit setting error in the timer configuration. Timer appears to be too fast

bit setting error in the timer configuration. LEDs were not working simply
because board_autoled_initialize() was not being called in the board startup
logic.
LEDs were not working simply because board_autoled_initialize() was not being
called in the board startup logic.
At this point, I would say that the basic NSH port is complete.
