David Brownell <david-b@pacbell.net>:

Add configuration for an old AT91rm9200 board, the Cogent CSB 337.
Worth noting from the OpenOCD perspective:

 - It got a real hardware trace port connector; wired up here as
   much as we can, lacking inexpensive trace-aware dongles.

 - This is the first in-tree use of the "arm920t cp15" command.
   It adjusts the CPU clocking and enables i-cache, which gives
   more than 4x speedup after booting Linux; it's visible even
   just running U-Boot.
