From 9b78ef0c7997052e9eaa0f7a4513d546fa17358c Mon Sep 17 00:00:00 2001
From: Mikhail Zhilkin <csharper2005@gmail.com>
Date: Sun, 29 May 2022 11:07:14 +0000
Subject: [PATCH] mtd: parsers: add support for Sercomm partitions
This adds an MTD partition parser for the Sercomm partition table that
is used in some Beeline, Netgear and Sercomm routers.
The Sercomm partition map table contains real partition offsets, which
may differ from device to device depending on the number and location of
bad blocks on NAND.
Original patch (proposed by NOGUCHI Hiroshi):
