So, not *unhappy* with them, but definitely some review is needed.
Also, there are aspects of the implementation that will need to be
generalized a bit.  For example, the sunxi code uses a magic register
in its implementation that allows a core to come out of reset at a known
(ie, given) non-0 address.  My A9 core has CPUs coming out of reset
at a fixed address of 0.  That means my "secure text" must be at 0,
and it must have a "secure vector" with a "secure reset" laid down at 0.
Ultimately, this means that a small modification (adding a secure vector
text section) to the LDS file will be needed to ensure that it is placed at 0
within the secure text section itself.

No, I don't have all this working quite yet. :-)
