I'm trying to create a initramfs for the Marvell OpenRD-client as Raúl 
Porcel did for the SheevaPlug in his acclaimed tome:

I've created a topic "Help with initramfs for Marvell OpenRD-Client LE" 
in the forum,, 
outlining what I have done and the failure I have met with:

    tftpboot 0x8000000 initramfs
    ## Loading Ramdisk Image at 08000000 ...
    Bad Magic Number

My question that could be readily answered is:  when preparing the 
initramfs for a staged tree at /usr/src/initramfs, is the command

    cd /usr/src/initramfs/
    find . -print0 | cpio --null -ov --format=newc | gzip -9 > [outputfile]

I'm wondering if the file should be in gzip format or something else?

Also, I read at the deprecated

    Additionally, you should enable SquashFS because most modern Gentoo 
Installation CDs require it.

Does this apply to a kernel for the ARM processor such as Raul did?

It would be really educational to learn what the steps are for creating 
an initramfs.
