I deliberately haven't connected it to the build, yet, as these
machines need the problem of the netboot device being left opened
by the loader properly fixed. I thought I had a proper MI fix for
this but re-reading the commit message that turned on the open-
close-dance for every file access back on I think that the U-Boot
support probably is abusing the closes to do post-transfer cleanup
thus requiring the current behavior. Currently I'm waiting for
raj@ to confirm whether this is the case so we can check other
options.
