	The A72 U-Boot code loads and boots a number of remote processors including the C71x DSP, both the C66_0 and C66_1 DSPs, and the various Main R5FSS Cores. In order to view the code loaded by the U-Boot by remote cores, U-Boot should configure the memory region with right memory attributes. Right now U-Boot carves out a memory region which is not sufficient for all the images to be loaded. So, increase this carve out region by 256MB.
