Subject: [PATCH] ARM: dts: keystone-evm: add spi nor flash support
Date: Mon, 12 May 2014 16:02:37 +0300 [thread overview]
Message-ID: <1399899757-15767-1-git-send-email-grygorii.strashko@ti.com> (raw)
From: Murali Karicheri <m-karicheri2-l0cyMroinI0@public.gmane.org>
k2hk, k2e, k2l EVM board have the same Micron N25Q128A11
SPI NOR Flash installed on SPI0 bus.
The NOR Flash is splitted on two partistions:
partition@0
label = "u-boot-spl";
reg = <0x0 0x80000>;
partition@1
label = "misc";
reg = <0x80000 0xf80000>;
Hence, add SPI NOR Flash nodes to all k2hk, k2e, k2l EVM boards.
