The code is doing monolithic reads for all chunks except the last one
which is wrong since a monolithic read will issue the
READ0+ADDRS+READ_START sequence. It not only takes longer because it
forces the NAND chip to reload the page content into its internal
cache, but by doing that we also reset the column pointer to 0, which
means we'll always read the first chunk instead of moving to the next
one.
Rework the code to do a monolithic read only for the first chunk,
then switch to naked reads for all intermediate chunks and finally
issue a last naked read for the last chunk.
Fixes: 02f26ecf8c mtd: nand: add reworked Marvell NAND controller driver

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
