/* 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.
