Please can you update whichever of the docs are relevant as part of this
patch i.e. One or more of misc/arm/booting.txt,
misc/arm/device-tree/booting.txt or misc/efi.markdown might plausibly
need updates to describe the new precedence for where a command line
will be taken from.

http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot will 
also need updating at some point.

How does this interact with the presence/absence of a config file and
any potential options= in that?

What about the "efi options" like "-cfg=" which are currently handled
from the UEFI command line, are they still correctly handled? (looks
like the others are -help and -basevideo)

Ian.
