From 781551df57c792aee291cd80a6aca24cd56cdd71 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 7 Dec 2012 09:06:59 +0100 Subject: misc: Add Lattice ECP3 FPGA configuration via SPI This patch adds support for bitstream configuration (programming / loading) of the Lattice ECP3 FPGA's via the SPI bus. Here an example on my custom MPC5200 based board: $ echo 1 > /sys/class/firmware/spi0.0/loading $ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data $ echo 0 > /sys/class/firmware/spi0.0/loading leads to these messages: lattice-ecp3 spi0.0: FPGA Lattice ECP3-35 detected lattice-ecp3 spi0.0: Configuring the FPGA... lattice-ecp3 spi0.0: FPGA succesfully configured!
