This patch series adds support for SPI socket on Willem EPROM programmer to rayer_spi driver. Tested with PCB4.0 with W25X16 chip (which is not supported by the original Windows-only software).
This patch series require 2013-03-06 rayer_spi patches by Kyösti Mälkki.
P.S. As the rayer_spi driver becomes more generic, it should probably be renamed (e.g. lpt_spi).
