This series breaks boot in K2HK evm. Below is the log.

U-Boot 2017.05-00088-g1743d040b1 (Jun 08 2017 - 10:38:00 +0530)

CPU: 66AK2Hx SR1.1
Model: Texas Instruments Keystone 2 Kepler/Hawking EVM
DRAM:  Cannot read DIMM params
Sorry, I don't know how to configure DDR3A.
Bye :(


Can you please look at it.

Thanks and regards,
