Hello,

Please use Chapter 1 (Porting U-Boot from an i.MX 6/7 Reference Board to

an i.MX 6/7 Custom Board) of "i.MX_BSP_Porting_Guide.pdf" in Linux docs.

< http://www.nxp.com/webapp/Download?colCode=L3.14.52_1.1.0_LINUX_DOCS >

Also, the following may be helpful.

"Freescale i.MX6 DRAM Port Application Guide-DDR3"

< https://community.freescale.com/docs/DOC-101708 >

Have a great day,
Yuri
