From 9cde66b8221841d62c7ad5901af9d2bed81d9e75 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 1 Feb 2016 12:41:53 +0000 Subject: kernel: mtdsplit: support Seama entity with UBI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some D-Link routers (e.g. DIR-885L) have NAND and use Seama format. It means OpenWrt will want to have UBI in Sseama entity and should be able to detect it.
