What is Freescale-specific about the concept of reserving memory for a secure monitor?
The PPA is a Freescale implementation of TrustZone application.
That does not answer the question. What is so special here that you cannot use the existing CONFIG_PRAM ?
CONFIG_PRAM is reserved from the top of u-boot memory, which is not necessarily the real top of memory.
I am putting this reserved memory under the name CONFIG_FSL_PPA_RESERVED_DRAM_SIZE for now, because I don't know if this will serve other SoCs. I would use a generic solution if I don't have MC and debug server in my way. I am open to suggestions.
