Re: kwuartboot on DreamPlug success
[Moving this discussion to debian-arm to keep others in the loop,
this is regarding booting a DreamPlug from UART using Leigh's kwuartboot
which you can find at http://www.solinno.co.uk/public/kwuartboot/]

OK, I've done that. However, I still need to tack the magic header on to
u-boot.bin to get it to recognise the image. So, what is this magic header,
and shouldn't kwuartboot be doing that for me?
FYI, I've updated my U-boot tree to the 2011.09 release, it seems Jason's
DreamPlug patches haven't made it in there yet.
