Hi Eric,

first, do you really want the "Resend" in the subject?

Could you check if the file clock.c has already a global

struct imx_ccm_reg *imx_ccm = (struct imx_ccm_reg *)CCM_BASE_ADDR;

definition, so this redefinition of "struct imx_ccm_reg *const 
imx_ccm" should (must?) be removed here? See

http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=arch/arm/cpu/armv7/mx6/clock.c;h=ef98563ff7639a3895e5dc00acd9cc30bb3c6772;hb=HEAD#l37

Trying to compile this I had to remove this on my test branch [1].

Best regards

Dirk
