[U-Boot] [RFC PATCH v1 0/2] Make most DDR non-secure in MMU while keep a small block secure

This set is to change MMU tables so DDR is in non-secure mode that
non-secure master such as SDHC DMA can access the data. To mix
secure and non-secure MMU entries, the MMU tables themselves have
to be in secure memory. A small portion memory is reserved at the
end of DDR (before debug server and MC) to host secure application
and the MMU tables.

Changes in v1:
  Initial patch.
  Depends on http://patchwork.ozlabs.org/patch/540248/
