For example, memory-region in .dts as below,
reg = <0x0 0x50000000 0x0 0x20000000>
We can get below values,
struct resource r;
r.start = 0x50000000;
r.end = 0x6fffffff;
So the size should be:
size = r.end - r.start + 1 = 0x20000000

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 Restructured Text 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.
