From 359f5e539036db4f7ac69a6d1c3fb7fe70266ffd Mon Sep 17 00:00:00 2001 From: Roger Pueyo Centelles Date: Mon, 24 Dec 2018 15:39:32 +0100 Subject: [PATCH] kernel: mtd: add support for EN25QH64 in spi-nor.c The Eon EN25QH64 is a 64 Mbit SPI NOR flash memory chip. Its 32, 128 and 256 Mbits siblings are supported upstream but this particular size wasn't. This commit includes patches for kernels 4.14 and 4.19. Tested on a COMFAST CF-E120A v3 (ath79).
