This patch adds a CONFIG entry for the default size of TrustZone DRAM that a board-port can over-ride. The region that U-Boot sets aside for the OPTEE run-time should be verified before attempting to hand off to the OPTEE run-time. Each board-port should carefully ensure that the TZDRAM size specified in the OPTEE build and the TZDRAM size specified in U-Boot match-up. Further patches will use TZDRAM size with other defines and variables to carry out a degree of automated verification in U-Boot prior to trying to boot an OPTEE image.
