Which processor / board is this? Normally U-Boot will report an error
and time out if it cannot send ethernet packets (at least this is
what it does on all boards I can test).

If it hangs this is an error in U-Boot which must be fixed no matter
if you can or want to use DHCP in Linux.

There is no such version.
Is the same problem present in the current version (i. e. top of tree

Ummm... where exactly is the problem? See Documentation/nfsroot.txt
