The A72 U-Boot code supports early load and boot of a number of remote processors including the C66_0 and C66_1 DSPs. The current code supports only loading into the DDR regions which were already given the appropriate memory attributes. The C66 DSPs also have L1 and L2 internal memory regions that can behave as normal-memories. Add a new entry to the J721E MMU table covering these regions with the appropriate memory attributes to allow the A72 U-Boot code to support loading directly into these memory regions.
