This is first step in migrating to a generic i.MX target which in the next steps will also get divided into arch-specific subtargets. In the result, this will make it possible to support, within a single target, also other modern NXP i.MX families, like the i.MX 7, i.MX 8 or recently introduced i.MX 9.
