From ad6c6361f9f85f7cf6f53558d109c82de73743a5 Mon Sep 17 00:00:00 2001 From: Michal Cieslakiewicz Date: Tue, 12 Nov 2019 14:02:14 +0100 Subject: [PATCH] ath79: enable all space on Netgear ar9344-based WNDR routers Netgear WNDR routers (AR9344 models) like WNDR4300 have 128 MiB of flash memory but only first 32 MiB are used now - both by vendor's firmware and OpenWrt. This patch concatenates two regions of flash memory: ubi part of firmware partition and reserved (unused) space beyond 'caldata_backup' while preserving ART backup. No data is wiped or moved away. This increases area for OS ubi volumes from 23 to 119 Megabytes.
