Dear Friends,

I am using u-boot and it is first loading into the ram from flash and then
starts booting. The problem is its taking a lot of time in loading the image
from flash to ram and then starts booting from it. Following is the output
for printenv variables. I am new to u-boot and thus not much aware of it. On
other board there is redboot installed and it loads kernel in just flash and
starts booting the kernel.

Kindly let me know if you need any information.

Thank you,
Ankur.
