* STMicroelectronics Parallel ATA STEM board
*
* This code assumes that STEM_notCS0 and STEM_notINTR0 lines are used,
* so jumpers J1 and J2 shall be set to 1-2 positions.
*
* Some additional main board setup may be required to use proper CS signal
* signal - see "arch/sh/include/mach-<board>/mach/stem.h" for more
* information.
