+LS1012A2G5RDB board Overview
+-----------------------
+ - SERDES Connections, 3 lanes supporting:
+      - SGMII, SGMII 2.5
+      - SATA 3.0
+ - DDR Controller
+     - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
+ -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
+ signals to
+    - QSPI NOR flash memory
+ - USB 3.0
+    - one high-speed USB 2.0/3.0 port.
+ - SDIO WiFi, SPI
+ - 2 I2C controllers
+ - One SATA onboard connectors
+ - UART
+   - The LS1012A processor consists of two UART controllers,
+   out of which only UART1 is used on 2G5RDB.
+ - ARM JTAG support
