Md Sadre Alam ee000969f2 mtd: rawnand: qcom: Pass 18 bit offset from NANDc base to BAM base
The BAM command descriptor provides only 18 bits to specify the BAM
register offset. Additionally, in the BAM command descriptor, the BAM
register offset is supposed to be specified as "(NANDc base - BAM base)
+ reg_off". Since, the BAM controller expecting the value in the form of
"NANDc base - BAM base", so that added a new field 'bam_offset' in the NAND
properties structure and use it while preparing the command descriptor.

Previously, the driver was specifying the NANDc base address in the BAM
command descriptor.

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.
