2 * U-boot - Configuration file for CSP Minotaur board
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').
11 * 0x00000000 u-boot bootstrap
12 * 0x00010000 environment
13 * 0x00020000 u-boot code
14 * 0x00030000 uImage.initramfs
