Yeah, all the other similar envvars are part of the board configuration
in the u-boot source. We could start trying to upstream a patch for each
platform to define an address for Xen, but I don't know how well it
would go down, or we could try and (ab)use e.g. $script_addr.

For now I prefer to just add it to the hostdb and the relevant wiki page
for the platform.

Ian.
