There are separate 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

Build instructions:
===================
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
