Dear Graeme Russ,

The common coe should be architecture-neutral.  It might cann
architecture-specific routines, which may (or may not) get added
later, depending if somebody cares about adding such support.

I have to admit that I never understood the fuzz about being able to
boot zImages.  I see more disadvanatges than advantages for this, but
some ARM people go frenzy when this topic pops up - see recent
discussions about removal of uImage support on the AKML.

Frankly: I see no benefit in adding x86 support.

I see no benefit in adding ARM support either, but YMMV...

Best regards,
