[PATCH v9 0/2] fpga: Lattice MachXO2 Slave SPI FPGA Manager support

From: Paolo Pisati
Date: Mon Apr 02 2018 - 11:13:58 EST


Hi all,
this series adds support for the Lattice MachXO2 FPGA chip, programmed
over slave SPI.

Tested on a raspberry pi3, beaglebone black (little endian mode) and imx6
hummingboard (big endian mode) + bugblat's pif2 fpga hat (machxo2 7000HC) or
tinyfpga A1/A2 (machxo2 256HC / 1200HC), in SPI slave mode with varying bus
speed.

Changes since v8:
* style fixes pointed out by Alan
* rebase on the new fpga_mgr_register() API
