[PATCH v2 1/2] mtd: spi-nor: Add support for EN25Q80A
From: Schrempf Frieder
Date: Mon Feb 18 2019 - 07:04:49 EST
From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>
This adds support for the EON EN25Q80A, a 8Mb SPI NOR chip.
It is used on i.MX6 boards by Kontron Electronics GmbH
(N60xx, N61xx).
It was only tested with a single data line connected, by writing and
reading random data with dd.
Signed-off-by: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>

Changes in v2:
==============
* Add information about boards using the chip and testing to the commit
message
* Remove SPI_NOR_QUAD_READ as the chip does not support 1_1_4 read
command (0x6b)
* Move the entry after en25q64 for alphabetical order
