-Subject: [PATCH 07/18] ARM: dts: Fix up the D-Link DIR-685 MTD partition info
-
-The vendor firmware was analyzed to get the right idea about
-this flash layout. /proc/mtd contains:
-
-dev:    size   erasesize  name
-mtd0: 01e7ff40 00020000 "rootfs"
-mtd1: 01f40000 00020000 "upgrade"
-mtd2: 00040000 00020000 "rgdb"
-mtd3: 00020000 00020000 "nvram"
-mtd4: 00040000 00020000 "RedBoot"
-mtd5: 00020000 00020000 "LangPack"
-mtd6: 02000000 00020000 "flash"
-
-Here "flash" is obviously the whole device and we know "rootfs"
-is a bogus hack to point to a squashfs rootfs inside of the main
-"upgrade partition". We know "RedBoot" is the first 0x40000 of
-the flash and the "upgrade" partition follows from 0x40000 to
-0x1f8000. So we have mtd0, 1, 4 and 6 covered.
-
-Remains:
-mtd2: 00040000 00020000 "rgdb"
-mtd3: 00020000 00020000 "nvram"
-mtd5: 00020000 00020000 "LangPack"
-
-Inspecting the flash at 0x1f8000 and 0x1fa000 reveals each of
-these starting with "RGCFG1" so we assume 0x1f8000-1fbfff is
-"rgdb" of 0x40000.
