3QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
4development platform, with a complete debugging environment.
5The LS1012ARDB board supports the QorIQ LS1012A processor and is
6optimized to support the high-bandwidth DDR3L memory and
7a full complement of high-speed SerDes ports.

14LS1012ARDB board Overview
15-----------------------
16 - SERDES Connections, 4 lanes supporting:
17      - PCI Express - 3.0
18      - SGMII, SGMII 2.5
19      - SATA 3.0
20 - DDR Controller
21     - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
22 -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
23 signals to
24    - QSPI NOR flash memory (2 virtual banks)
25    - the QSPI emulator.s
26 - USB 3.0
27    - one high-speed USB 2.0/3.0 port.
28 - Two enhanced secure digital host controllers:
29    - SDHC1 controller can be connected to onboard SDHC connector
30    - SDHC2 controller: Three dual 1:4 mux/demux devices,
31    74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC,
32    SDIO WiFi, SPI, and Ardiuno shield
33 - 2 I2C controllers
34 - One SATA onboard connectors
35 - UART
36   - The LS1012A processor consists of two UART controllers,
37   out of which only UART1 is used on RDB.
38 - ARM JTAG support
