Hi Deepak,
Actually we are planning to include a new parameter as version of parameter.
This sounds like mata-programming, although I'm pretty sure that you wnat to do something simple - so obviously I did not understand what you want to do, sorry.
I have a tentative idea of writing into the nand flash as a env variable so that i will be able to read it from the u-boot and then from kernel. But im not sure of how to do this. do u have any idea if this is possible.
Much is possible, but I do not understand what exactly you are trying to do. Maybe you tell us what "high level" goal you try to achieve and then we can decide for ourselves if an environment variable is the way to go here or if other more natural solutions come to mind.
Also how do i add a new env variable in u-boot...
setenv newvariable newvalue
Cheers Detlev
