IEEE 1394 support for haiku

1. Introduction

	  These directories contains IEEE1394(FireWire) driver which is my 
	GSOC2007 project work under my mentor Jerome Duval's guidance.
	Please note this driver is still under development. You can find latest 
	version from Haiku's repository:

	The driver consists of 13 parts:
	
	DIRECTORY: src/add-ons/kernel/bus_managers/firewire/
	- fwohci.c/fwohci_pci.c
		OHCI driver
			- IEEE1394 link/phy chip control
	- firewire.c
		Chip independent driver 
			- CSR
			- Transaction
			- Bus management
	- fwdma.c
		allocate memory and other convenient functions for DMA.

	- fwmem.c
		physical memory of a remote node.

	- firewire_module.c
		implementation of firewire module interfaces

	- util.c
		memory allocation. Copied from haiku's rtl8169 driver
	
	- timer.c
		timer implemetation. Copied from haiku's rtl8169 driver
	
	- fwcrom.c(This file is in src/bin/fwcontrol directory)
		handle with config rom
	
	DIRECTORY: src/add-ons/kernel/drivers/bus/firewire/
	
	- fw_raw.c
		Character devices for userland
	
	DIRECTORY: src/bin/fwcontrol/

	- fwcontrol.c (userland)
		Bus management function for user. 
		show topology map, change gap count, bus reset, etc.
	
	- eui64.c
		handle with EUI64 ID
	
	- fwdv.c
		dv format support
	
	- fwmpegts.c
		mpegts format support

2. Installation

	- svn up to update the source
	- jam -q firewire.
	- jam -q fw_raw
	- jam -q fwcontrol
	- jam -q dpc(This file is in src/add-ons/kernel/generic/dpc)
	- cp the firewire to haiku's /system/add-ons/kernel/bus_managers
	- cp the dpc to haiku's /system/add-ons/kernel/generic
	- cp the fw_raw to haiku's drivers/bin and make a softlink in drivers/dev

3. DV
	I have tested my minidv: MV920. It works OK.

4. SBP
	This support is still under development

5. Tested HW

	OS
	- HAIKU/i386

	* Not tested on SMP.
	* Not tested on big-endian machine...

	OHCI
	- Texas Instruments TSB12LV26 (PCI)

	* There might be phy probing problem but most of the OHCI
	  chips should work.

	Physical layer chip
	- This does not matter, most physical layer chip should work

6. Example
	fwcontrol 
	Output a list of devices that are connected to the bus

	fwcontrol -t
	Show the topology map

	fwcontrol -c 0
	Show the config rom of node 0

	fwcontrol -r
	trigger bus reset

	fwcontrol -R mini.dv
	Receive DV or MPEG TS stream and save it in mini.dv. Press Ctrl-C to
	stop receiving data.
	Note: the program will try to guess which mode first
	
	fwcontrol -M d -R mini.dv
	Explicitly specify receiving via DV mode.
