/*
* 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
