[U-Boot] Can't erase or read NOR using mtd part-id

[Alexandre Gambier <a.gambier@ftemaximal.fr>]

Hello,

thanks for your reply.
I'm running u-boot 1.3.1. I got it from STLinux.

I will try to set CONFIG_JFFS2.
But does it mean it will erase the partition using JFFS2 ?
Will it support to read and write the environment settings with this 
file format ?
