/*
* 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
