Subject: [PATCH v2 1/2] mtd: spi-nor: Add support for EN25Q80A

From: Frieder Schrempf <[email protected]>

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 <[email protected]>
---
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
