Request for information : How to modify MAX SDRAM
Hi,
I'm trying to add a new architecture to uboot. What is the process and there is a documentation ?
It's an icybox nas6220-b which is similar to sheevaplug, except for memory size and nand limit.
wiki.nas-portal.org/index.php/IB-NAS6220-B www.raidsonic.de/data/products/icybox/IB-NAS6220/datasheet_ib-nas6220_e.pdf
How can I limit the sheevaplug configuration memory and ram size limit ?
Cheers,
