Hi:

        I use i.MX6 Series SABRE,   u-boot-2009.08,linux-3.0.35

 

        I had modified mx6q_sabresd.h in uboot:

              #define CONFIG_CMD_SATA

             #undef CONFIG_FSL_ENV_IN_MMC

             #define CONFIG_FSL_ENV_IN_SATA

       after uboot boot,printf:

U-Boot 2009.08 (Dec 10 2014 - 15:15:43)

please check GPR13 in linux:

linux source code(arch/arm/mach-mx6/board-mx6q_sabresd.c)

and make the same settings in UBoot:

board/freescale/mx6q_sabresd/mx6q_sabresd.c

Also in Uboot check CCM CG2 register CCM_CCGR5 so sata clock

will be enabled.

May be useful to check GPR13 in Uboot and Linux.

Best regards
