BBB GPMC & PRU: HOW TO XFR 8MB/s from FIFO to DDR3

[mike.f...@gmail.com]

Demonstrate how to perform a sustained transfer from (an FPGA) FIFO to the BBB DDR3 using GPMC and PRU0.  First part of the How-To uses CCS8 and the JTAG interface to run code on the CortexA8 and PRU0.  Performance demonstrated is 8MB/s (32bit words, 2000K transfers per second) . The second part of the How-to documents how the design was migrated to a Debian OS for integration into a usable product.
