-Fixed Partitions
-================
-
-Partitions can be represented by sub-nodes of a flash device. This can be used
-on platforms which have strong conventions about which portions of a flash are
-used for what purposes, but which don't use an on-flash partition table such
-as RedBoot.
-
-The partition table should be a subnode of the flash node and should be named
-'partitions'. This node should have the following property:
-- compatible : (required) must be "fixed-partitions"
-Partitions are then defined in subnodes of the partitions node.
+Deprecated: partitions defined in flash node
+============================================
 
 For backwards compatibility partitions as direct subnodes of the flash device are
 supported. This use is discouraged.
 NOTE: also for backwards compatibility, direct subnodes that have a compatible
 string are not considered partitions, as they may be used for other bindings.
-
-#address-cells & #size-cells must both be present in the partitions subnode of the
-flash device. There are two valid values for both:
-<1>: for partitions that require a single 32-bit cell to represent their
-     size/address (aka the value is below 4 GiB)
-<2>: for partitions that require two 32-bit cells to represent their
-     size/address (aka the value is 4 GiB or greater).
-
-Required properties:
-- reg : The partition's offset and size within the flash
-
-Optional properties:
-- label : The label / name for this partition.  If omitted, the label is taken
-  from the node name (excluding the unit address).
-- read-only : This parameter, if present, is a hint to Linux that this
-  partition should only be mounted read-only. This is usually used for flash
-  partitions containing early-boot firmware images or data which should not be
-  clobbered.
-- lock : Do not unlock the partition at initialization time (not supported on
-  all devices)
-- slc-mode: This parameter, if present, allows one to emulate SLC mode on a
-  partition attached to an MLC NAND thus making this partition immune to
-  paired-pages corruptions
