Initial support for Nomadik 8815 development board
The NMDK8815 board is distributed by ST Microelectornics.
Other (proprietary) code must be run to unlock the CPU before
U-Boot runs. doc/README.nmdk8815 outlines the boot sequence.
This is the initial port, with basic infrastructure and
a working serial port.
