I am working on the BT Home Hub 3A at the moment (arx100, nand-based 
board), and have also found that asc images build correctly but
nandspl images do not.

There seem to a number of problems. For a start some of the make 
targets seem to be missing. The following fixed that for arx100,
and I think that a similar fix is necessary for danube and vrx200
too.

Then the ebu configuration word needs to be set in the nandspl
image, as it is for norspl. Once again, the following fixed that
for arx100, and I think something similar will be required for danube
and vrx200.

Finally the ltq-boot-image tool adds a couple of download header to the
final image which I don't think should be there.

Daniel, does all the above make sense?

That said, even after making those changes my nandspl images still
don't work.
