Add PIXIS FPGA support for MPC8641HPCN board.
Move the 8641HPCN's PIXIS code to the new directory board/freescale/common/ as it will be shared by future boards not in the same processor family. Write a "pixis_reset" command that utilizes the FPGA reset sequencer to support alternate soft-reset options such as using the "alternate" flash bank, enabling the watch dog, or choosing different CPU frequencies. Add documentation for the pixis_reset to README.mpc8641hpcn. Signed-off-by: Haiying Wang <haiying.wang@freescale.com> Signed-off-by: Jon Loeliger <jdl@freescale.com>
