Overview
--------
The T1040RDB is a Freescale reference board that hosts the T1040 SoC
(and variants). Variants inclued T1042 presonality of T1040, in which
case T1040RDB can also be called T1042RDB.

The T1042RDB_PI is a Freescale reference board that hosts the T1042 SoC.
(a personality of T1040 SoC). The board is similar to T1040RDB but is
designed specially with low power features targeted for Printing Image Market.
