The K2HK board is based on Texas Instruments Keystone2 family of SoCs: K2H, K2K.
More details on these SoCs are available at company websites
K2H: http://www.ti.com/product/tci6638k2h
The K2E SoC details are available at

There are only 2 eth port installed on the boards.
Board configuration files:
include/configs/k2hk_evm.h
include/configs/k2e_evm.h
+include/configs/k2l_evm.h
As u-boot is migrating to Kconfig there is also board defconfig files
configs/k2e_evm_defconfig
configs/k2hk_evm_defconfig
+configs/k2l_evm_defconfig
Supported boot modes:
- SPI NOR boot
- AEMIF NAND boot
+ - UART boot
Supported image formats:
- - u-boot.bin: for loading and running u-boot.bin through Texas instruments
- code composure studio (CCS)
+ - u-boot-dtb.bin: for loading and running u-boot-dtb.bin through
+ Texas Instruments code composure studio (CCS) and for UART boot.
- 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
+ - MLO: gpimage for programming AEMIF NAND flash for NAND boot
Build instructions:
===================
-Examples for k2hk, for k2e just replace k2hk prefix accordingly.
+Examples for k2hk, for k2e and k2l just replace k2hk prefix accordingly.
Don't forget to add ARCH=arm and CROSS_COMPILE.

+Load and Run U-Boot on keystone EVMs using UART download
+========================================================
+
+Open BMC and regular UART terminals.
+
+1. On the regular UART port start xmodem transfer of the u-boot-dtb.bin
+2. Using BMC terminal set the ARM-UART bootmode and reboot the EVM
+ BMC> bootmode #4
+ MBC> reboot
+3. When xmodem is complete you should see the u-boot starts on the UART port
