+ * 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
