Host Controller Version 4.10 re-defines SDMA System Address register as 32-bit Block Count for v4 mode, and SDMA uses ADMA System Address register (05Fh-058h) instead if v4 mode is enabled. Also when using 32-bit block count, 16-bit block count register need to be set to zero. Since using 32-bit Block Count would cause problems for auto-cmd23, it can be chosen via host->quirk2.

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.
