board/freescale: use the common genimage template
The boards imx6dlsabreauto, imx6dlsabresd, imx6qsabreauto, imx6qsabresd, imx6sxsabresd were referring to board/freescale/create-boot-sd.sh for the sdcard image generation. This commit: * Removes board/freescale/create-boot-sd.sh * Uses the common Freescale genimage template instead. The offset of the first partition was 1MB in the script and is modified to 8MB in the template. * Fixes the readme.txt file accordingly Signed-off-by: Georges Savoundararadj <savoundg@gmail.com> Cc: Fabio Estevam <festevam@gmail.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Peter Korsgaard <peter@korsgaard.com> Cc: Yann E.
