[Buildroot] [PATCH] imx/genimage: Place the rootfs at a proper offset when BR2_LINUX_KERNEL_INSTALL_TARGET=y

[Fabio Estevam]

Currently, when BR2_LINUX_KERNEL_INSTALL_TARGET=y is selected, issuing
a "saveenv" command in the U-Boot prompt may lead to rootfs corruption.

Avoid this problem by placing the rootfs at an 8MB offset, just like
it is done in genimage.cfg.template.

Tested on a imx6qp-wandboard and also on a custom imx6ull based board.

"saveenv" does not corrupt the rootfs anymore after this change.
