Enabling the distro options
---------------------------
+In your board's defconfig, enable the DISTRO_DEFAULTS option by adding
+a line with "CONFIG_DISTRO_DEFAULTS=y". If you want to enable this
+from Kconfig itself, for e.g. all boards using a specific SoC then
+add a "default y if ARCH_FOO" to the DISTRO_DEFAULTS section of
+the Kconfig file in the root of the u-boot sources.

In your board configuration file, include the following:
------------------------------------------------------------
#ifndef CONFIG_SPL_BUILD
-#include <config_distro_defaults.h>
#include <config_distro_bootcmd.h>
#endif
------------------------------------------------------------
specific boot.scr scripts are enabled. This enables distros to generate a
U-Boot-specific boot.scr script rather than extlinux.conf as the boot
configuration file. While doing so is fully supported, and
-<config_distro_defaults.h> exposes enough parameterization to boot.scr to
+CONFIG_DISTRO_DEFAULTS exposes enough parameterization to boot.scr to
allow for board-agnostic boot.scr content, this document recommends that
distros generate extlinux.conf rather than boot.scr. extlinux.conf is intended
to work across multiple bootloaders, whereas boot.scr will only work with
