[U-Boot] Request for information : How to modify MAX SDRAM

[U-Boot] Request for information : How to modify MAX SDRAM

[Gérald Kerma]

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,
