Thu Sep 19 19:00:05 EST 2013
Add support for T104x board in board file t104x_qds.c, It is common for
both T1040 and T1042 as they share same QDS board.
T1040QDS board Overview
-----------------------
- SERDES Connections, 8 lanes supporting:
— PCI Express: supporting Gen 1 and Gen 2;
— SGMII
— QSGMII
— SATA 2.0
— Aurora debug with dedicated connectors (T1040 only)
- DDR Controller
- Supports rates of up to 1600 MHz data-rate
- Supports one DDR3LP UDIMM/RDIMMs, of single-, dual- or quad-rank types.
-IFC/Local Bus
- NAND flash: 8-bit, async, up to 2GB.
- NOR: 8-bit or 16-bit, non-multiplexed, up to 512MB
- GASIC: Simple (minimal) target within Qixis FPGA
- PromJET rapid memory download support
- Ethernet
- Two on-board RGMII 10/100/1G ethernet ports.
- PHY #0 remains powered up during deep-sleep (T1040 only)
- QIXIS System Logic FPGA
- Clocks
- System and DDR clock (SYSCLK, “DDRCLK”)
- SERDES clocks
- Power Supplies
- Video
- DIU supports video at up to 1280x1024x32bpp
- USB
- Supports two USB 2.0 ports with integrated PHYs
— Two type A ports with 5V at 1.5A per port.
— Second port can be converted to OTG mini-AB
- SDHC
- SDHC port connects directly to an adapter card slot, featuring:
- Supporting SD slots for: SD, SDHC (1x, 4x, 8x) and/or MMC
— Supporting eMMC memory devices
- SPI
- On-board support of 3 different devices and sizes
- Other IO
- Two Serial ports
- ProfiBus port
- Four I2C ports
Add T104xQDS support in Kconfig and Makefile. Also create device tree.
