/* The LPC3131 has 192Kb of ISRAM beginning at virtual address 0x1102:8000.
 * LPC31xx boot ROM expects the boot image be compiled with entry point at
 * 0x1102:9000.  A 128b header will appear at this address (applied by
 * lpc313xImgCreator) and the executable code must begin at 0x1102:9080.
 *
 * The .text vitual address space begins at the same location as the physical
 * address space:  0x1102 8000.  The virtual space is broken up into three
 * regions:
 *
 *                                           PHYSICAL         VIRTUAL
 *   NAME    DESCRIPTION                 SIZE    START    SIZE    START
 *  -------- -------------------------- ----- ----------- ------- -----------
 *   locked  Pages locked in memory.     48Kb 0x1102 8000  48Kb   0x1102 8000
 *   paged   Pages in nonvolatile store. 96Kb 0x1103 4000 384Kb   0x1103 4000
 *   data    .data/.bss/heap.            32Kb 0x1104 c000  32Kb   0x1109 4000
 *           Reserved for page table     16Kb 0x1105 4000  16Kb   0x1109 c000
 *  -------- -------------------------- ----- ----------- ------- -----------
 *                                       192Kb 0x1105 8000 480Kb   0x110a 0000
 *
 * These region sizes must match the size in pages specified for each region
 * in the NuttX configuration file:  CONFIG_PAGING_NLOCKED, CONFIG_PAGING_NVPAGED,
 * and CONFIG_PAGING_NDATA.
 *
 * NOTE 1: The locked region is really big here so that you can enable lots of
 * debug output without overflowing the locked region.  32Kb would probably be
 * plenty if this were a real, optimized application.
 *
 * NOTE 2: Different compilers will compile the code to different sizes.  If you
 * get a link time error saying that the locked region is full, you may have to
 * re-organize this memory layout (here and in defconfig) to make the locked
 * region even bigger.
