Well, my problem is that I am really short of ram.
So I would like to have my filesystem in flash and keep it in flash.

So I would like to have my root filesytem in flash ( possible ?? ).
romfs seems to be a way to do it.

It think the way to do it it to declare my romfs as initrd ( maybe I am
wrong because initrd is init ram disk and it means that it MUST be a RW
filesystem in RAM ??? )

After reading sources of U Boot it seems that if I put a second parameter at
bootm, it is going to copy the initrd into RAM ( right ? ).
whereas I would like to keep my romfs in flash.

maybe I misunderstand and misuse completly the initrd... Help and hints
welcome...

Chris
