Bin Meng75574052016-02-05 19:30:11 -08002 * U-Boot - Configuration file for CSP Minotaur board
Mike Frysingerb704a202008-10-12 23:16:52 -04003 *
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:
10 *
11 * 0x00000000 u-boot bootstrap
12 * 0x00010000 environment
13 * 0x00020000 u-boot code
14 * 0x00030000 uImage.initramfs
