Re: [U-Boot] [PATCH 1/2] mx28evk: extend default environment

Dear Fabio Estevam,

From: Otavio Salvador otavio@ossystems.com.br

The environment has been based on mx53loco but keeping the possibility to easy change the default console device as Freescale and mainline kernels differ on the device name.

Can we possibly unify it with what's already in m28evk? Also, it'd be cool if we had some default -- very generic -- env. Can we go in that direction?
