Subject: [U-Boot] U-boot env variables parsing

Hi!

I am doing env settings some thing like this,

ROOT1=/dev/mmcblk0p1
ROOT2=/dev/mmcblk0p2
ROOT=${ROOT1}
bootargs1=console=ttyS0,115200n8 mem=256M noinitrd rw rootdelay=1 ${ROOT}

when I say 'setenv bootargs ${bootargs1}', ${ROOT} gets resolved to 'ROOT1', it does not get completely resolved to '/dev/mmcblk0p1'. 

Is there something fundamentally wrong in setting the env variables this way?

What would be the right way to achieve this, as I want ROOT to be ${ROOT1} sometimes and ${ROOT2} some times?

regards

-Nitin
