Hi, all:

   our product is based on SDK_3.0.35, recently I'm trying update the uboot and kernel to SDK_3.0.17(yocto build).

    for uboot in SDK_3.0.35, there is one post help people turn on MMU support to speed up uboot:

Linux Fast Boot on i.MX6 Sabresd Board

    but when I move to uboot in SDK_3.10.17(yocto version v2014.01-r0), there is no "board_mmu_init( )" uboot_src/board/freescale/mx6sabresd/mx6sabresd.c.

can some one give me some instruction how to turn on MMU for uboot on SDK_3.10.17? I'll appreciate any kind of helps.

You don't need to do this is in the board file like in the old FSL 2009.08 U-boot. Common code will do this for you.

Hi Wally

I think you can look at ..arch/arm/lib/cache-cp15.c

Best regards
