We are already using u-boot (ppcboot) on our custom board with a 405GPr. 
U-boot is stored in a 1MB NOR Flash, linux kernel and FS into
We want to use a 440EP for the next generation of products.
It includes direct nand flash controller and is able to boot from this 
nand ( Execute a linear sequence
of boot code out of single page of first block (512B)).
Is it possible  to run U-boot from Nand flash ?
(In this case no more NOR flash is needed on my board)
Does anyone have some experience with 440EP nand flash controller and 
Probably a better solution is to use a nor flash for U-Boot and use the 
440EP nand flash controller to provide
a glue less interface between 440EP and Nand devices (used to store linux 
kernel and FS).
Any advice about U-BOOT and 440EP is welcome.
