From b2154e8a1d456875122cbbff2a18e5e1c55ef4d2 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Sun, 14 Jan 2018 17:35:33 +0100 Subject: digilent_spi: add a driver for the iCEblink40 development board This is driver that supports the Lattice iCE40 evaluation kits. On the board is a SPI flash memory chip labeled ST 25P10VP. Tested to work read/write/erase with "-p digilent_spi -c M25P10" or with a patch that resets the part beforehands (in which case it gets detected as a M25P10-A and is way faster due to paged writes).
