/* The SAMA5D3x-EK has 128MB of NOR flash at CS0 (0x1000:0000).  In this
 * configuration, the .text and a copy of the .data section will be loaded
 * into NOR flash.  NuttX .data, .bss, the IDLE stack, and the primary
 * heap will be allocated in SRAM.  The SAMA5D3 has 128 KB of ISRAM beginning
 * at virtual address 0x0030:0000.
 *
 * Vectors in low memory are assumed to reside at the beginning of NOR flash
 * 16KB of ISRAM is reserved at the beginning of ISRAM for the page table.
