well, you mean to run a u-boot out of a running u-boot?
U-Boot is not designed to do so. But some devices may allow you to just
run a newer u-boot from a running one (at91;). You need to know that
u-boot set up your SDRAM timings which destroys the content of the DRAM.
So if your new u-boot is located there it can not be executed.
I dunno if the kirkwood can do so, but I think they can not. You will need
a) a JTAG
b) another boot device, for example USB, MMC, whichever device the
kirwood SoC can read from its ROM code (I do not know)
to de-brick it.

Please ask some kirkwood specialist or google, there are a lot of
sheevaplug hackers out there, one of them may be able to help you here.
