Copy SDRAM to flash and IAP memory reservation

For IAP (In-app programming) to update firmware code to Flash Bank of a LPC43xx, do I need to write from SDRAM to SRAM to flash bank memory or can I just write from SDRAM->flash


Another question I have is in UM10503.pdf section " RAM used by IAP command handler", it looks like there's a requirement to reserve some RAM block for IAP commands.  What's the total size of memory application must reserve for IAP calls and is there some code example for this reservation for IAP? Appreciate your help.
