Subject: [PATCH] mtd: bcm47xxpart: add of_match_table with a new DT binding

This allows using bcm47xxpart parser to find partitions on flash
|
||
|
|
described in DT using the "brcm,bcm947xx-cfe-partitions" compatible
|
||
|
|
property. It means this parser doesn't have to be explicitly selected by
|
||
|
|
a flash driver anymore. It can be used e.g. together with a generic
|
||
|
|
m25p80 / spi-nor if device is just properly described.
