[U-Boot] [U-Boot:RESEND][[PATCH 6/7] k2hk: add support for k2hk SOC and EVM

Murali Karicheri m-karicheri2 at ti.com
Sat Feb 8 00:23:13 CET 2014


k2hk EVM is based on Texas Instruments Keystone2 Hawking/Kepler
SoC. Keystone2 SoC has ARM v7 Cortex-A15 MPCore processor. Please
refer the ti/k2hk_evm/README for details on the board, build and other
information.

This patch add support for keystone architecture and k2hk evm.

+U-Boot port for Texas Instruments XTCIEVMK2X
+============================================
+
+Author: Murali Karicheri <m-karicheri2 at 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
+
+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
+
+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
