I'm porting the 3.10.17_beta bsp to our custom board that is running an i.MX6Solo with a single bank of lpddr2, we used the sabresd as a reference board. When the kernel boots I see the following message:
NET: Registered protocol family 1
RPC: Registered named UNIX socket transport module.
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.

Tracing this code I see the busfreq-imx6 driver calling init_mmdc_ddr3_settings() for any processor other than the imx6sl. Have there been any new patches to add support for lpddr2 on processors other than imx6sl? The system boots fine, are there any known issues running the board in this state?
