title: Partition
|
|
|
|
description: |
|
|
This binding describes a single flash partition. Each partition must have its
|
|
relative offset and size specified. Depending on partition function extra
|
|
properties can be used.
|
|
|
|
A partition may be dynamically allocated by a specific parser at runtime.
|
|
In this specific case, a specific suffix is required to the node name.
|
|
Everything after 'partition-' will be used as the partition name to compare
|
|
with the one dynamically allocated by the specific parser.
|
|
If the partition contains invalid char a label can be provided that will
|
|
be used instead of the node name to make the comparison.
|
|
This is used to assign an OF node to the dynamiccally allocated partition
|
|
so that subsystem like NVMEM can provide an OF node and declare NVMEM cells.
|
|
The OF node will be assigned only if the partition label declared match the
|
|
one assigned by the parser at runtime.
