Booting Ebony-evb with u-boot and linux-devel-sourcetree from Denx

Hi all,

I am trying to boot my Ebony-evb with u-boot and a kernel image generated from devel-sourcetree from Denx. It seems to me like the kernel image simply ignores the parameters handed over by u-boot. I also found some earlier threads
that support my thoughts. Unfortunately I am bound to u-boot and I am not able
to switch back to the native bootloader that comes with the evb. Has anyone already a system up and running booted by u-boot? At first it does not matter whether
the root filesystem comes from flash or over nfs. Any hints would be appreciated.

Thanks in advance

Markus

If somebody has time to support u-boot properly, I'd be happy to apply the patch to the ebony port. The current port relies on OpenBIOS since it gathers the MAC addresses from the defined VPD space. Some people run with u-boot/ebony, but I gather they just hack the MAC address code and use the kernel cmdline option.

It would be nice if somebody submitted a patch to make it u-boot friendly, it's just not high on my TODO list.

We also were trying to get this to work, however, the ebony setup ignores the uboot parameters...so, unless you modify the code, you're stuck with this...

However, you could configure the kernel with boot parameters hard coded...that's what we are currently doing.
