Let me ask about how to build U-Boot with enabling eMMC Fast boot mode.
My customer is facing to build u-boot.
They want to be sure that the u-boot has a feature for load kernel image with eMMC fastboot.
They found a definition of “CONFIG_FSL_FASTBOOT” in your u-boot source code including your following BSP code. (in mx6sxsabresd.c)
git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.52-1.1.0_ga
And they think that CONFIG_FSL_FASTBOOT should be defined for u-boot to have a feature to load kernel image with eMMC fastboot.
Is it true?
