[U-Boot] [PATCH] imx: mx6q_4x_mt41j128.cfg: Setup CCM_CCOSR register

[prem s]

Hi all,

I am working on IMX6Q-SabreLite Board.in that board we have sgtl5000
codec.so I would like to add (sgtl5000) codec support in *u-boot level*.There
is no code available in u-boot level for this codec.Can you please help me
How to initialize this audio codec and how to test this one in UBOOT level.

It will be very helpful if you send any u-boot level patch for this
codec(sgtl5000).

Thanks
Prem.
