Add support for partition table defined in Device Tree. Similar to how it's done with MTD, add support for defining a fixed partition table in device tree. A common scenario for this is fixed block (eMMC) embedded devices that have no MBR or GPT partition table to save storage space. Bootloader access the block device with absolute address of data. This is to complete the functionality with an equivalent implementation with providing partition table with bootargs, for case where the booargs can't be modified and tweaking the Device Tree is the only solution to have an usabe partition table. The implementation follow the fixed-partitions parser used on MTD devices where a "partitions" node is expected to be declared with "fixed-partitions" compatible in the OF node of the disk device (mmc-card for eMMC for example) and each child node declare a label and a reg with offset and size. If label is not declared, the node name is used as fallback. Eventually is also possible to declare the read-only property to flag the partition as read-only.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
