.Nm intro
|
|
.Nd introduction to evbarm special files and hardware support
|
|
.Sh DESCRIPTION
|
|
The evbarm port is really a collection of ports of
|
|
.Nx
|
|
to a range of development and evaluation boards based on the ARM Architecture.
|
|
.Pp
|
|
This section describes the supported boards, the special files,
|
|
related driver functions, and networking support available in each system.
|
|
In this part of the manual, the
|
|
.Tn SYNOPSIS
|
|
section of
|
|
each configurable device gives a sample specification
|
|
for use in constructing a system description for the
|
|
.Xr config 1
|
|
program.
|
|
The
|
|
.Tn DIAGNOSTICS
|
|
section lists messages which may appear on the console
|
|
and/or in the system error log
|
|
.Pa /var/log/messages
|
|
due to errors in device operation;
|
|
see
|
|
.Xr syslogd 8
|
|
for more information.
|
|
.Pp
|
|
This section contains both devices
|
|
which may be configured into the system
|
|
and network related information.
|
|
The networking support is introduced in
|
|
.Xr netintro 4 .
|
|
.Sh SUPPORTED BOARDS
|
|
Each supported board requires a custom kernel for that board.
|
|
.Pp
|
|
The following boards are currently supported by the evbarm configuration:
|
|
.Pp
|
|
.Bl -tag -width Integrator -offset indent -compact
|
|
.It Integrator
|
|
The Integrator/AP development system from ARM Ltd.
|
|
Supported processor boards
|
|
include the CM10200E and CM920T.
|
|
.It IQ80310

|
|
.It IQ80321
|
|
The reference platform for the XScale-based IOP321 I/O processor from Intel.
|
|
.It Npwr
|
|
The Npwr board, from Team ASA, is based on the IOP310 processor from Intel and
|
|
targetted at the network-attached storage space.
|
|
.It IXM1200
|
|
The reference platform for the XScale-based IXP1200 Network processor from
|
|
Intel.
|
|
.It SMDK2410
|
|
The reference platform for the ARM920T-based S3C2410 processor from Samsung.
|
|
.It SMDK2800
|
|
The reference platform for the ARM920T-based S3C2800 processor from Samsung.
|
|
.It BRH
|
|
The BRH (Big Red Head) is an evaluation and development platform from ADI
|
|
Engineering, based on the XScale-based I80200 processor
|
|
.It NTNP425B
|
|
An evaluation and development platform from NOVATEC, using the XScale-based
|
|
IXP425 processor.
|
|
.It DBPXA250
|
|
An evaluation and development platfrom from Intel, using the XScale-based
|
|
PXA250 processor.
|
|
.El
|
|
.Sh DEVICE SUPPORT
|
|
This section describes some of the hardware supported on the various boards.
|
|
Software support for these devices comes in two forms.
|
|
A hardware
|
|
device may be supported with a character or block
|
|
.Em device driver ,
|
|
or it may be used within the networking subsystem and have a
|
|
.Em network interface driver .
|
|
Block and character devices are accessed through files in the file
|
|
system of a special type; see
|
|
.Xr mknod 8 .
|
|
Network interfaces are indirectly accessed through the interprocess
|
|
communication facilities provided by the system; see
|
|
.Xr socket 2 .
|
|
.Pp
|
|
A hardware device is identified to the system at configuration time
|
|
and the appropriate device or network interface driver is then compiled
|
|
into the system.
|
|
When the resultant system is booted, the
|
|
autoconfiguration facilities in the system probe for the device
|
|
and, if found, enable the software support for it.
|
|
If a device does not respond at autoconfiguration
|
|
time it is not accessible at any time afterwards.
|
|
To enable a device which did not autoconfigure,
|
|
the system must be rebooted.
|
|
.Pp
|
|
The autoconfiguration system is described in
|
|
.Xr autoconf 4 .
|
|
A list of the supported devices is given below.
|
|
.Sh LIST OF DEVICES
|
|
The devices listed below are supported in this incarnation of
|
|
the system.
|
|
Devices are indicated by their functional interface.
|
|
Not all supported devices are listed.
