   2 * U-Boot - Configuration file for CSP Minotaur board
   3 *
   4 * Thu Oct 25 15:30:44 CEST 2007 <hackfin@section5.ch>
   5 *    Minotaur config, brushed up for official uClinux dist.
   6 *    Parallel flash support disabled, SPI flash boot command
   7 *    added ('run flashboot').
   8 *
   9 * Flash image map:
