From a08561ffdfb13986e2628296ccfd42f8a273b729 Mon Sep 17 00:00:00 2001
From: Lee Jones <lee.jones@linaro.org>
Date: Tue, 16 Feb 2016 13:53:47 +0000
Subject: [PATCH] ARM: stm32: Supply a DTS file for the STM32F469 Discovery
board
It's pretty similar to the STM32F429, but there are some
subtle changes required to boot successfully.
Signed-off-by: Lee Jones <lee.jones@linaro.org>
[Thomas: remove rdinit= from /chosen/bootargs.]
