** "Real Mode" operation refers to U2/Uturn chip operation.
** U2/Uturn were designed to perform coherency checks w/o using
** the I/O MMU - basically what x86 does.
**
** Philipp Rumpf has a "Real Mode" driver for PCX-W machines at:
** CVSROOT=:pserver:anonymous@198.186.203.37:/cvsroot/linux-parisc
** cvs -z3 co linux/arch/parisc/kernel/dma-rm.c
**
** I've rewritten his code to work under TPG's tree. See ccio-rm-dma.c.
**
** Drawbacks of using Real Mode are:
** o outbound DMA is slower - U2 won't prefetch data (GSC+ XQL signal).
** o Inbound DMA less efficient - U2 can't use DMA_FAST attribute.
