SRICHARAN R - March 24, 2013, 6:24 a.m.
The boot.scr has to be built and copied, where as allowing
to import the environment from a text file is much more
friendly.

Thanks to the below patch, which has much more informative
change log.

commit: d70f54808dfa83b574e1239c3eccbcf3317343e1
(omap4: allow the use of a plain text env file instead boot scripts)
