.PP
.PP
\fBide_build_dmatable\fR prepares a dma request. We map the command
to get the pci bus addresses of the buffers and then build up
the PRD table that the IDE layer wants to be fed. The code
knows about the 64K wrap bug in the CS5530.
.PP
Returns the number of built PRD entries if all went okay,
returns 0 otherwise.

May also be invoked from trm290.c
