1.3.2.3. NAND Flash Devices
The NAND subsystem reserves at least the first 1 MB on the NAND device. If the NAND flash device has blocks greater than 256 KB, then the NAND subsystem reserves the first four blocks on the device. For a NAND device with less than 256 KB block size, the second-stage boot loader image must be placed in multiple blocks. The NAND subsystem expects to find up to four second-stage boot loader images on the NAND device. You may have less than four images if required. The second-stage boot loader image should always be at the start of a physical page. Because a block is the smallest area used for erase operation, any update to a particular image does not affect other images.
