max_req_size is calculated by 'max_blk_size * max_blk_count' in the TMIO core. So, specifying U32_MAX as max_blk_count will overflow this calculation. It will cause no harm in practice because the immense high number will overflow into another immense high number. However, it is not good coding practice, so calculate max_blk_count so that max_req_size will fit into unsigned int on ARM32/64. Thanks to the Renesas BSP team for the bug report!

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.
