Make sure that MX51_PAD_GPIO1_1 does not remain configure as ALT0/SD1_WP (it is out of reset). This is needed because of external pull-up resistor attached to that pad that, when left unchanged, will drive SD1_WP high preventing eSDHC1/eMMC from working correctly. To fix that add a pinmux configuration line configureing the pad to function as a GPIO. While we are at it, add a corresponding output-high GPIO hog in an effort to minimize current consumption.

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.
