The ARM UARTs are the take away I had from conversations with Julien
Grall and reading past comments on the ML how people can change the ARM
UARTs. Obviously if that's not desired I can drop that. I originally had
them enabled as they are in config/arm{32,64}.mk and changed them to be
user configurable later in the series.

As far as KEXEC goes, its a user configurable option now in Rules.mk.
You can build "make kexec=n" and it will disable it. I chose that one as
an original example in v1 of how a user configurable option would look
in this scheme.
