[PATCH v1 1/1] env: fat: Allow overriding interface, device and partition

[何勇]

Hi:
Override the env_fat_get_dev_part function in the board file, you can 
load env from sdcard or emmc without modifying any configuration 
of u-boot, it is very useful for  building wic firmware by yocto. 


it has been done under env/ext4.c
