RZ/G2LC SoM has both 64 GB eMMC and microSD connected to SDHI0. Both these interfaces are mutually exclusive and the SD0 device selection is based on the XOR between GPIO_SD0_DEV_SEL and SW1[2] switch position. This patch sets GPIO_SD0_DEV_SEL to high in DT. Use the below switch setting logic for device selection between eMMC and microSD slot connected to SDHI0. Set SW1[2] to position OFF for selecting eMMC Set SW1[2] to position ON for selecting microSD This patch enables eMMC on RZ/G2LC SMARC platform by default.

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.
