[U-Boot] [PATCH] nitrogen6x : Use generic distro configuration

In order to simplify the use of various images on various media
for nitrogen6x, the configuration of the board must follow the
generic distro configuration (doc/README.distro).
In order to boot your old rootfs, move your kernel and your device
tree in /boot/. Then create /boot/extlinux/extlinux.conf with for
example:
default Buildroot
label Buildroot
kernel /boot/zImage
append console=ttymxc1,115200 root=/dev/mmcblk0p1 rootwait rw
fdtdir /boot

to switch from command line mode to communication mode, and when the

+3. Using generic distro configuration
+-------------------------------------
+
+In order to simplify the use of various images on various media
+for imx6 boards, the configuration of the board must follow the
+generic distro configuration (doc/README.distro).
+
+3.1. Setup uboot configuration for your board
+---------------------------------------------
+
+First, you have to set 'CONFIG_DISTRO_DEFAULTS=y' in your board defconfig
+
+Some mandatory variable are set in mx6_common.h but can be overwritten like:
+ - fdtfile with CONFIG_FDTFILE
+ - fdt_addr_r and fdt_addr with CONFIG_FDTADDR
+ - ramdisk_addr_r, ramdiskaddr CONFIG_RAMDISKADDR
+
+You also have to define BOOT_TARGET_DEVICES with available media.
+For example added in include/configs/nitrogen6x.h:
+#define BOOT_TARGET_DEVICES(func) \
+ func(MMC, mmc, 0) \
+ func(MMC, mmc, 1) \
+ func(SATA, sata, 0) \
+ func(USB, usb, 0) \
+ func(PXE, pxe, na) \
+ func(DHCP, dhcp, na)
+
+All this configuration should be done before '#include "mx6_common.h"'
+
+3.2. Setup your distribution
+----------------------------
+
+Set the partition containing /boot/ bootable.
+Copy your kernel and device tree in /boot.
+Create /boot/extlinux/extlinux.conf on your rootfs and fill it according to specification
+at http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
+
+For example:
+
+default Buildroot
+
+label Buildroot
+ kernel /boot/zImage
+ append console=ttymxc1,115200 root=/dev/mmcblk0p1 rootwait rw
+ fdtdir /boot
+
