FILECORE disklabels


Would anyone object to the following change to allow arm kernels to leave
out FILECORE disklabel support ?

It is a change I have had locally for a while now.

The current situation, whereby all ARM platforms have FileCore boot block 
support, is clearly silly.  I don't think, though, that making it 
dependent on FILECORE is the right approach.  The ability to mount 
FileCore partitions should be independent of the ability to find 
non-FileCore partitions on shared disks.

A better approach (and one more in keeping with NetBSD's usual one) would 
be to only have support for FileCore boot blocks on those MACHINEs that 
natively run RISC OS, which would be acorn26, acorn32, and iyonix.

Eventually, this all wants to be beaten into the wedges framework, of 
course.
