   4     *  Board device initialization              File: ptswarm_devs.c
   5     *
   6     *  This is the "C" part of the board support package.  The
   7     *  routines to create and initialize the console, wire up
   8     *  device drivers, and do other customization live here.
   9     *
  10     *  Author:  Mitch Lichtenberg (mpl@broadcom.com)
  11     *
  12     *  modification history
  13     *  --------------------
  14     *  01h,07apr02,gtb  incorporate CSWARM board_show_cpu_type() changes.
  15     *  01g,31jan02,jmb  incorporate Mitch's CSWARM changes.
  16     *  01f,23jan02,jmb  add a read-only flash driver so that CFE can open
  17     *                   flash while running in the same flash.
  18     *  01e,21jan02,jmb  read environment variables from NVRAM even in SAFE mode
  19     *  01d,07jan02,jmb  new flash installation arg, multi-chip support
  20     *                   resizing of CS0-1 depending on boot device.
  21     *  01c,20dec01,jmb  don't move CS0 to nonstandard address
  22     *  01b,19dec01,jmb  remap CS0 for easy access of 16M flash in boot area
  23     *  01a,14dec01,jmb  derived from cswarm_devs.  Changed the startflags
  24     *                   table to support 3 different consoles, including
  25     *                   an external uart device.
