Subject: lantiq: fritz7362sl: add partition subnode for SPI flash
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a6222738760b9ab796ac0f69d6df8b3f2b9c2f26;p=openwrt%2Fstaging%2Fxback.git

lantiq: fritz7362sl: add partition subnode for SPI flash

Without a partition subnode ofpart_core still parses direct subnodes as
partitions, but it ignores nodes with a compatible property. Due to
this, the switch to nvmem-cells made the urlader partition inaccessible.
As a result, the wireless network was broken, as the calibration data
is read from that partition by a script.

Fixes: #8983
