configs/stm32f469_disco: new configuration for STM32F469 Discovery board

Browse Source 
Similar to stm32f429_disco, this commit adds a configuration for the
Cortex-M4 based STM32F469 platform.

It requires a few kernel patches, which have already been submitted
upstream, as well as a small OpenOCD patch. Besides that, it re-uses
most of what has been added for the STM32F429 platform.

Signed-off-by: Lee Jones <lee.jones@linaro.org>
[Thomas:
 - squash multiple patches from Lee Jones into one
 - improve the readme.txt file
 - sync the defconfig with the adaptations made to the stm32f429
   configuration.]

It's pretty similar to the STM32F429, but there are some
subtle changes required to boot successfully.

Subject: [PATCH] ARM: configs: Add new config fragment to change RAM start
point
Rather than duplicate a defconfig for each difference
between platforms, we can choose to pick a basic defconfig and
manipulate it at run-time using config fragments. Here we're
adding a new fragment to over-ride the RAM start point to 0x0.

STM32F469 Discovery
===================
This tutorial describes how to use the predefined Buildroot
configuration for the STM32F469 Discovery evaluation platform.
Building
--------
make stm32f469_disco_defconfig
make
Flashing
--------
./board/stmicroelectronics/stm32f469-disco/flash.sh output/
It will flash the minimal bootloader, the Device Tree Blob, and the
kernel image which includes the root filesystem as initramfs.
