2 | * U-boot - Configuration file for CSP Minotaur board | |
3 | * | |
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: | |

11 | * 0x00000000 u-boot bootstrap | |
12 | * 0x00010000 environment | |
13 | * 0x00020000 u-boot code | |
14 | * 0x00030000 uImage.initramfs | |
