/*
 * U-boot - Configuration file for CSP Minotaur board
 *
 * Thu Oct 25 15:30:44 CEST 2007 <hackfin@section5.ch>
 *    Minotaur config, brushed up for official uClinux dist.
 *    Parallel flash support disabled, SPI flash boot command
 *    added ('run flashboot').
 *
 * Flash image map:
 *
 * 0x00000000      u-boot bootstrap
 * 0x00010000      environment
 * 0x00020000      u-boot code
 * 0x00030000      uImage.initramfs
