Hello Sergey,

Thanks for this patch. A few questions below.

Why do you introduce a genimage.cfg file? It is identical to the one in
board/freescale/common/imx/genimage.cfg.template_no_boot_part_spl,
which I believe is already being used in the current defconfig.

Could you use:

BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT=y
BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT_SOURCE="board/udoo/mx6qdl/boot.scr.txt"

You will still need a post-build.sh script to copy from BINARIES_DIR to
TARGET_DIR/boot, though.

Even if you cannot use for some reason the common post-image script
from board/freescale/common/imx/, you could still use the generic
support/scripts/genimage.sh... which you're anyway doing in a later
commit.

As asked above, any reason to no longer use this post-image script ?

Thanks!
