Generic command line -v2

Hi all,

new in -v2
	* Updated with some changes to adding spaces from Christophe Leroy.
	* Added OF support with comments from Rob on my 2015 submission which he reviewed.
		(https://lore.kernel.org/patchwork/patch/604997/)
	  Christophe and Rob suggested to have support for this inside the OF code.
	* Powerpc was made to use the OF parts instead of having changes into it's code.
	* Removed trim effect from powerpc config files. sed only was used to convert.
	  requested by Michael Ellerman.

That's basically it. Otherwise the same changes.

Daniel
