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.
