[PATCH 1/2] doc: dt: mtd: add w25q64 to list of supported SPI flashes

[Franklin S Cooper Jr]

From: Sekhar Nori <nsekhar@ti.com>

W25Q64 is found on TI's AM335x ICEv2 board. Add it to list
for supported SPI flash devices. This flash can be identified
using JEDEC READ ID opcode.

[PATCH 2/2] ARM: dts: am335x-icev2: Add SPI based NOR

[Franklin S Cooper Jr]

Enable support for W25Q64CVSSIG which is a Winbond 64 Mbit SPI NOR.

At boot you will see the following message:
m25p80 spi1.0: found s25fl064k, expected w25q64

This is because the JEDEC ID for this chip is the same as s25fl064k.
However, this should be harmless since both chips are essentially the
same.

Applying both into omap-for-v4.12/dt-v2 branch.

Thanks,
