The page address register describes the page address of the starting
address for NAND read/write/erase operations.
According to the manual, it consists of two parts:
{chip select, page number}
The `chip select` is fixed at 2 bits, and the `page number` is
determined based on the actual capacity of the single-chip memory.
Therefore we need to determine the `chip select` bits base on the `page
number`.
For example, for a 1GB capacity chip (2K page size), it has 1M pages.
Thus, [19:0] is used to represent the page number, and [21:20]
represents the chip select.

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.
