[PATCH 2/2][v2] powerpc/fsl-booke: Add initial T1042RDB_PI board support
From: Priyanka Jain <hidden>
Date: 2014-07-31 10:16:38
Subsystem:
linux for powerpc (32-bit and 64-bit), linux for powerpc embedded ppc85xx, the rest · Maintainers:
Madhavan Srinivasan, Scott Wood, Linus Torvalds
T1042RDB_PI is Freescale Reference Design Board supporting the T1042
QorIQ Power Architecture™ processor. T1042 is a reduced personality
of T1040 SoC without Integrated 8-port Gigabit. The board is designed
with low power features targeted for Printing Image Market.
T1042RDB_PI is similar to T1040RDB board with few differences like
it has video interface, supports T1042 personality only
