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!
