From 787ecdf66de6798540fb8b756404566341b4733c Mon Sep 17 00:00:00 2001 From: Felix Baumann Date: Fri, 31 Mar 2023 06:16:04 +0200 Subject: [PATCH] ramips: mt7621: ASUS RT-AX53U add NMBM, nest firmware Nests kernel and ubi into firmware partition in-order to be compatible with OEM firmware. This allows restoring oem firmware from a backup of firmware2. Add jffs2 partition which is present in the oem firmware. Add support for mediatek NMBM (wear leveling on newer mediatek devices). Exclude UBI partition from NMBM management. Continues PR #10685.
