From f2bf06fd785de154ab96545b98952fb079310f35 Mon Sep 17 00:00:00 2001 From: Julien Boibessot Date: Tue, 21 Dec 2010 18:38:07 +0100 Subject: ubifs: Add UBI image generation support. UBI images are generated from UBIFS one (with ubinize tool) and are used by bootloaders (eg U-Boot) to write UBIFS images directly on bare NAND FLASH (see http://www.linux-mtd.infradead.org/faq/ubi.html).
