-1. 2GB DDR3 (can support 8GB SO DIMM as well)
-2. 512M NAND (over ti emif16 bus)
-3. 6MB MSM SRAM (part of the SoC)
-4. two 1GBit Ethernet ports (SoC supports upto 4)
-5. two UART ports
-6. three i2c interfaces
-7. three spi interfaces (only 1 interface supported in driver)
+There are only 2 eth port installed on the boards.
-There are seperate PLLs to drive clocks to Tetris ARM and Peripherals.

To bring up SMP Linux on this board, there is a boot monitor
code that will be installed in MSMC SRAM. There is command available
to install this image from u-boot.

- u-boot.bin: for loading and running u-boot.bin through Texas instruments
code composure studio (CCS)
- u-boot-spi.gph: gpimage for programming SPI NOR flash for SPI NOR boot
Build instructions:
===================
+Examples for k2hk, for k2e just replace k2hk prefix accordingly.
+Don't forget to add ARCH=arm and CROSS_COMPILE.
To build u-boot.bin
- >make k2hk_evm_config
+ >make k2hk_evm_defconfig
>make u-boot-spi.gph
To build u-boot-spi.gph
