All Freescale processors used in this target are capable to detect error
and correction. [1] It can not be used as kernel module. [2] This is
helpful to report hardware errors.

It enables three kernel options:

- EDAC, which is a subsystem
- EDAC_LEGACY_SYSFS, it enables sysfq nodes
- MP85XX, support for Freescale MPC8349, MPC8560, MPC8540, MPC8548, T4240

EDAC is already enabled for following targets:
qoriq, octeon, octeontx and zynq.
