|
.Sh SYNOPSIS
|
|
.Cd mfp0 at intio0 addr 0xe88000 size 0x2000 intr 64
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
drives Motorola MC68901 MFP (Multi-function Peripheral).
|
|
.Nm
|
|
driver is always required to run the
|
|
.Nx Ns /x68k
|
|
kernel, because it is connected to important devices such as
|
|
the display controller, and provides fundamental functions
|
|
like the system clock tick and interrupt controller.
|
|
Since
|
|
.Nm
|
|
provides many functions, most of the jobs as a
|
|
device driver is done by its child drivers such as
|
|
.Xr kbd 4
|
|
and
|
|
.Xr clock 4 .
|
|
.Nm
|
|
driver itself only provides the common way to access its
|
|
registers and a few utility functions for other non-child drivers.

|
|
.Sh BUGS
|
|
Machine-dependent part and machine-independent part should be split.
