Matrix Vision MergerBox
-----------------------

1.	Board Description

	The MergerBox is a 120x160mm single board computing platform
	for 3D Full-HD digital video processing.

	Power Supply is 10-32VDC.

2	System Components

2.1	CPU
	Freescale MPC8377 CPU running at 800MHz core and 333MHz csb.
	256 MByte DDR-II memory @ 333MHz data rate.
	64 MByte Nor Flash on local bus.
	1 GByte Nand Flash on FCM.
	1 Vitesse VSC8601 RGMII ethernet Phys.
	1 USB host controller over ULPI I/F with 4-Port hub.
	2 serial ports. Console running on ttyS0 @ 115200 8N1.
	1 mPCIe expansion slot (PCIe x1 + USB) used for Wifi/Bt.
	2 PCIe x1 busses on local mPCIe and cutom expansion connector.
	2 SATA host ports.
	System configuration (HRCW) is taken from I2C EEPROM.

2.2	Graphics
	SM107 emebedded video controller driving a 5" 800x480 TFT panel.
	Connected over 32-Bit/66MHz PCI utilizing 4 MByte embedded memory.

2.3	FPGA
	Altera Cyclone-IV EP4C115 with several PCI DMA engines.
	Connects to 7x Gennum 3G-SDI transceivers as video interconnect
	as well as a HDMI v1.4 compliant output for 3D monitoring.
	Utilizes two more DDR-II controllers providing 256MB memory.

2.4	I2C
	Bus1:
		AD7418 @ 0x50 for voltage/temp. monitoring.
		SX8650 @ 0x90 touch controller for HMI.
		EEPROM @ 0xA0 for system setup (HRCW etc.) + vendor specifics.
	Bus2:
		mPCIe SMBus
		SiI9022A @ 0x72/0xC0 HDMI transmitter.
		TCA6416A @ 0x40 + 0x42 16-Bit I/O expander.

		DS1338C @ 0xD0 real-time clock with embedded crystal.
		9FG104 @ 0xDC 4x 100MHz LVDS SerDes reference clock.

3	Flash layout.

	reset vector is 0x00000100, i.e. low boot.

	00000000	u-boot binary.
	00100000	FPGA raw bit file.
	00300000	FIT image holding kernel, dtb and rescue squashfs.
	03d00000	u-boot environment.
	03e00000	splash image

	mtd partitions are propagated to linux kernel via device tree blob.
