Add support for QSPI on NXP layerscape LS1012A-RDB, LS1012A-QDS, LS1012A-FRDM and LS1012A-FRWY boards. LS1012A-RDB has 2 Spansion "s25fs512s" flashes of size 64M each and only one can be accessed at a time. LS1012A-QDS/FRDM has 1 spansion "s25fs512s" flash of size 64M. LS1012A-FRWY has one winbond "w25q16dw" flash of size 2M. Use generic compatibles as "jedec,spi-nor" for automatic detection of flash. Configure RX and TX buswidth values as 2 as only two I/O lines are available for data transfer. Add ls1012a(si) node alongwith flash nodes.

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.
