Moving boot to SPI flash. Having issues with DMA in mx233

We have a project with imx233, based on Olinuxino's maxi board (iMX233-OLinuXino-MAXI).

Normally it's booting from microsd, but we would like to move to nand flash. We have ordered ( SST25VF064C) chips from Microchip, which are 64mbit SPI flash chips.

The plan is to hook this up to SPI2.

 

What other things we should think about, besides changing the jumpers to boot from microsd to "SPI2 flash master", and to flash a suitable linux kernel and rootfs to that nand? Do we need to do some configuration/recompiling to bootlets ? Are there some good recommendations on the flashing procedure ?

Thanks for any advice, or tips - this is a first time project for us, so any advice is welcome, thanks!
