mtd: parsers: ofpart: limit parsing of deprecated DT syntax
For backward compatibility ofpart still supports the old syntax like:
spi-flash@0 {
compatible = "jedec,spi-nor";
reg = <0x0>;
partition@0 {
label = "bootloader";
reg = <0x0 0x100000>;
};
};
(without "partitions" subnode).
There is no reason however to support nested partitions without a clear
"compatible" string like:
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "bootloader";
reg = <0x0 0x100000>;
partition@0 {
label = "config";
reg = <0x80000 0x80000>;
};
};
};
(we never officially supported or documented that).
Make sure ofpart doesn't attempt to parse above.
