Uli,
Do you have a link to the kernel list discussion? At this point I am more
interested in getting cmdline support than in any particular implementation.
I did try your patch on top of mike's but I had no luck. One of the issues I
have run into is the BROKEN Sharp bootloader that makes things more
interesting. Mike's patches can work around this problem by setting up a
fake ATAG list at a non-standard location.

I would love to see more progress on this, since I would like to improve
support for booting devices from non-standard locations (ie SD card) without
custom kernels.

Thank you for your help,

Henry von Tresckow (hvontres)
