Thanks for the detailed review.

Fixed.

Agreed. I should have explained the reason.

RTAS:
      This package contains few tools (like nvram, ppc64_cpu, etc) which are not
       dependent on RTAS support. Traditionally we always had RTAS support (at least
       on IBM Power system). But now a days we do have environments like PowerNV 
host
       where we do not have RTAS support. Hence lets disable RTAS by default. If
       someone wants to build powerpc-utils with RTAS they can enable it.

I will add this to patch description.

Yep. I should have explored this option. Fixed in v2.

Yes. Its GPLv2.

Fixed.

Sure. Will send v2 soon.
