m8xx_cpm_hostalloc(), if it is anything like the 8260 version, enables you
to allocation memory from dual-port RAM. (which could be handy and/or
required for certain CPM related operations) _va() and _pa() only work for
main memory addresses. For all other address ranges the iopa() function must
be used. (I hope this is helpful)

With that said, I would be interested in your modifications if you are
willing to share.
