Re: Passing kernel arguments - SAMA5D4EK

Sascha,

Have you had a chance to look into what I need to do to convert to the
new environment?

Also, would it be beneficial to add the ability to load more than one
partition to the bootargs for the old environment setup?  I've almost
finished the boot script modifications to allow for it while still
being backwards compatible.  I can push it back up to the repository
when finished if interested.
