imx: introduce 'cortexa7' subtarget
This adds some essential files required by new 'cortexa7' subtarget, dedicated for Cortex-A7 based NXP i.MX series. For now, the kernel config-default focuses only on the i.MX 6UL family, as the following changeset will introduce support for i.MX 6ULL based device. Support for more platforms (e.g. i.MX 7) might be enabled later, while adding more devices. Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
