With the dreamplug, I often load u-boot into RAM via the JTAG (0x0600000
and 0x0800000), and then 'resume 0x0600000'.  Then use the u-boot
running from 0x0600000 to burn the image to SPI flash from 0x0800000.
But that's loaded via the JTAG, not from a running u-boot.

I think I posted instructions to this mailinglist a while ago about
this.  If you have the JTAG (it's only $35US), I would advise trying
that.

thx,

Jason.
