Looks like Keystone2 platform may have quite a few missing configurations for various SoC variants. We need mark each of these id as shared in corresponding registers as well, without doing this, drivers fail inexplicably since the drivers seem to expect SoC wide coherency capability - which needs to be configured explicitly.
Bootlog: k2g: http://pastebin.ubuntu.com/15480089/ k2hk: http://pastebin.ubuntu.com/15480090/
also tested on an slightly older bootloader on K2E/K2L as well: k2g: http://pastebin.ubuntu.com/15475588/ k2hk: http://pastebin.ubuntu.com/15475589/ k2l: http://pastebin.ubuntu.com/15478358/ k2e: http://pastebin.ubuntu.com/15478332/
This series is based on: master 0764f24ae6bc net: Move CONFIG_RTL8169 to Kconfig
NOTE: K2G still requires additional patches for fixing NAND to prevent data abort being registered early in the boot by u-boot wrong access to GPMC. (testing was performed using out-of-tree solution for this)
