You may use U-boot command “clocks” to get information about DDR frequency.

To change default after reset configuration of i.MX6, DCD table may be used.

Please look at the following :

“Need to modify the "flash_headers.h" file from u-boot for DDR3 modification”

Also, please refer to i.MX6 Reference Manual, boot chapter for more details.

Have a great day,
Yuri
