Installing the 21.02.0-rc1 Sysupgrade image on the TP-Link CPE510 v2 or TP-Link CPE610 v1 results in the same bootloop as reported in [[https://bugs.openwrt.org/index.php?do=details&task_id=3750|https://bugs.openwrt.org/index.php?do=details&task_id=3750]]

Here is a log from my device with a line length of 80 chars

When it was working the MTD blocks looked as follows and the firmware MTD partition was correctly split. This is not happening now resulting in the boot failure.

GKaURTbV:

Thanks for the bootlog on the CPE510 v2.

Makes one wonder why the "firmware" partition is not getting split into "kernel" + "rootfs" partitions for the CPE devices with 21.02.0-rc1..
