imx6sabresd: boot to /init in mfgtools mode
Buildroot supplies a nice /init wrapper script to use when booting from a ramdisk. We add a patch to u-boot to tell the kernel to boot into /init (instead of /linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a buildroot system entirely through USB.

+Subject: [PATCH] mx6qsabre_common: boot Linux to /init in mfgtools mode
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+Buildroot supplies a nice /init wrapper script to use when booting from a
+ramdisk.
+
+This patch tells u-boot to tell the kernel to boot into /init (instead of
+/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
+buildroot system entirely through USB.
