[U-Boot] [PATCH v3 1/2] imx: Introduce a header for the imx cpu versions
From: Fabio Estevam fabio.estevam@freescale.com
Instead of duplicating the CPU definitions at mx5 and mx6 sys_proto.h header files, introduce a common header to centralize such definitions.

Currently when we boot a mx6dual U-boot reports that it is a mx6quad.
Report it as MX6D instead:
