BOOTING from FLASH(QSPI)

Hi 

Here i am using RZ/A1H Free Rtos for my guiliani project. I used GSE guiliani for graphics development and created the resource files to flash graphics along with the application code developed using E2 Studio. Here i used 2 external flash(QSPI of 128MB(64MB*2 ))for BOOT.(To enable QSPI, JP18 must be shorted and SW6’s switches (SW6.1 – SW6.6) need to be set to:OFF, ON, OFF, ON, ON, ON.) using this SW switching pattern. And also i am not using any external flash for storage purpose and also no provision for that. Now i need to change the BOOTING from 2 external flashes to single flash of 64MB,Questions raised above for me is

1. Whether the Guiliani Resource and Guiliani Application files can be accommodated in 64MB or not?

2. How to change the QSPI BOOT of 2 flashes(QSPI1 & QSPI2) into single flash of QSPI1 ?

3. How can i utilize other QSPI2 flash to use as non volatile memory storage for my other data's. using normal SPI?
