Hi WD, I like your .sig, very appropriate today :-)

I acknowledge the wink in your response, but my thought here is that, if
you _really_ need to fit in 32K, you may want to run "tftpboot" (or
equiv) instead of hush so that all the gutted u-boot knows how to do is
boot linux over the network.  Kind of equivalent to replacing "init" in
a linux disk image so that it runs your application directly.

There were only two requirements specified by Terry: net boot and fit in
32K.  Hopefully he is an engineer per Dr. McCoy ;-).
