CONFIG_ATA=y 

CONFIG_ATA_VERBOSE_ERROR=y

$ setenv fec_addr 00:04:9f:00:ea:d3 

$ setenv loadaddr 0x70800000 

$ setenv rd_loadaddr 0x70D00000 

$ setenv bootcmd 'run bootcmd_sata; bootm ${loadaddr} ${rd_loadaddr}' 

$ setenv bootcmd_sata 'sata read 0 ${loadaddr} 0x800 0x2000; sata read 0 ${rd_loadaddr} 0x3000 0x300;' 

$ setenv bootargs console=ttymxc0 init=/init androidboot.console=ttymxc0 video=mxcdi1fb:RGB666,XGA ldb=di1 di1_primary ip=dhcp gpu_nommu, gpu_memory=64M 

$ saveenv
