+U-Boot port for Texas Instruments XTCIEVMK2X
+============================================
+
+Author: Murali Karicheri <m-karicheri2@ti.com>
+
+This README has information on the u-boot port for XTCIEVMK2X EVM board.
+Documentation for this board can be found at
+ http://www.advantech.com/Support/TI-EVM/EVMK2HX_sd.aspx
+
+The board is based on Texas Instruments Keystone2 family of SoCs : K2H, K2K.
+More details on these SoCs are available at company websites
+ K2K: http://www.ti.com/product/tci6638k2k
+ K2H: http://www.ti.com/product/tci6638k2h
+
+Board configuration:
+====================
+
+Some of the peripherals that are configured by u-boot are:-
+
+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 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.
+
+The port related files can be found at following folders
+ keystone2 SoC related files: arch/arm/cpu/armv7/keystone/
+ K2HK evm board files: board/ti/k2hk_evm/
+
+board configuration file: include/configs/k2hk_evm.h
+
+Supported boot modes:
+ - SPI NOR boot
+ - AEMIF NAND boot
+
+Supported image formats:-
+ - 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
+ - u-boot-nand.gph: gpimage for programming AEMIF NAND flash for NAND boot
+
+Build instructions:
+===================
+
+To build u-boot.bin
+ >make k2hk_evm_config
+ >make u-boot-spi.gph
+
+To build u-boot-spi.gph
+ >make k2hk_evm_config
+ >make u-boot-spi.gph
+
+To build u-boot-nand.gph
+ >make k2hk_evm_config
+ >make u-boot-nand.gph
+
+Load and Run U-Boot on K2HK EVM using CCS
+=========================================
+
+Need Code Composer Studio (CCS) installed on a PC to load and run u-boot.bin
+on EVM. See instructions at below link for installing CCS on a Windows PC.
+http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Getting_Started#
+Installing_Code_Composer_Studio
+Use u-boot.bin from the build folder for loading annd running u-boot binary
+on EVM. Follow instructions at
+http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup
+to configure SW1 dip switch to use "No Boot/JTAG DSP Little Endian Boot Mode"
+and Power ON the EVM. Follow instructions to connect serial port of EVM to
+PC and start TeraTerm or Hyper Terminal.
+
+Start CCS on a Windows machine and Launch Target
+configuration as instructed at http://processors.wiki.ti.com/index.php/
+MCSDK_UG_Chapter_Exploring#Loading_and_Running_U-Boot_on_EVM_through_CCS.
+The instructions provided in the above link uses a script for
+loading the u-boot binary on the target EVM. Instead do the following:-
+
+1. Right click to "Texas Instruments XDS2xx USB Emulator_0/CortexA15_1 core (D
+ isconnected: Unknown)" at the debug window (This is created once Target
+ configuration is launched) and select "Connect Target".
+2. Once target connect is successful, choose Tools->Load Memory option from the
+ top level menu. At the Load Memory window, choose the file u-boot.bin
+ through "Browse" button and click "next >" button. In the next window, enter
+ Start address as 0xc001000, choose Type-size "32 bits" and click "Finish"
+ button.
+3. Click View -> Registers from the top level menu to view registers window.
+4. From Registers, window expand "Core Registers" to view PC. Edit PC value
+ to be 0xc001000. From the "Run" top level menu, select "Free Run"
+5. The U-Boot prompt is shown at the Tera Term/ Hyper terminal console as
+ below and type any key to stop autoboot as instructed :=
+
+U-Boot 2014.04-rc1-00201-gc215b5a (Mar 21 2014 - 12:47:59)
+
+I2C: ready
+Detected SO-DIMM [SQR-SD3T-2G1333SED]
+DRAM: 1.1 GiB
+NAND: 512 MiB
+Net: K2HK_EMAC
+Warning: K2HK_EMAC using MAC address from net device
+, K2HK_EMAC1, K2HK_EMAC2, K2HK_EMAC3
+Hit any key to stop autoboot: 0
+
+SPI NOR Flash programming instructions
+======================================
+U-Boot image can be flashed to first 512KB of the NOR flash using following
+instructions:-
+
+1. Start CCS and run U-boot as described above.
+2. Suspend Target. Select Run -> Suspend from top level menu
+ CortexA15_1 (Free Running)"
+3. Load u-boot-spi.gph binary from build folder on to DDR address 0x87000000
+ through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
+ using CCS", but using address 0x87000000.
+4. Free Run the target as desribed earlier (step 4) to get u-boot prompt
+5. At the U-Boot console type following to setup u-boot environment variables.
+ setenv addr_uboot 0x87000000
+ setenv filesize <size in hex of u-boot-spi.gph rounded to hex 0x10000>
+ run burn_uboot_spi
+ Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
+ to "SPI Little Endian Boot mode" as per instruction at
+ http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup.
+6. Power ON the EVM. The EVM now boots with u-boot image on the NOR flash.
+
+AEMIF NAND Flash programming instructions
+======================================
+U-Boot image can be flashed to first 1024KB of the NAND flash using following
+instructions:-
+
+1. Start CCS and run U-boot as described above.
+2. Suspend Target. Select Run -> Suspend from top level menu
+ CortexA15_1 (Free Running)"
+3. Load u-boot-nand.gph binary from build folder on to DDR address 0x87000000
+ through CCS as described in step 2 of "Load and Run U-Boot on K2HK EVM
+ using CCS", but using address 0x87000000.
+4. Free Run the target as desribed earlier (step 4) to get u-boot prompt
+5. At the U-Boot console type following to setup u-boot environment variables.
+ setenv filesize <size in hex of u-boot-nand.gph rounded to hex 0x10000>
+ run burn_uboot_nand
+ Once u-boot prompt is available, Power OFF the EVM. Set the SW1 dip switch
+ to "ARM NAND Boot mode" as per instruction at
+ http://processors.wiki.ti.com/index.php/EVMK2H_Hardware_Setup.
+6. Power ON the EVM. The EVM now boots with u-boot image on the NAND flash.
