The Samsung Galaxy S III mini (GT-I8190) is a smartphone with Ux500 SoC released in 2012. Thanks to the great mainline support for Ux500, it can actually run mainline Linux quite well. Add a new device tree for it with support for: - Internal Storage (eMMC) - External Storage (Micro SD card) - UART - GPIO Buttons - Vibrator Note that the device tree cannot be booted directly with the original (Samsung) bootloader. It keeps the L2 cache turned on, which causes the kernel to hang shortly after decompression. As a workaround I have created a port of (mainline) U-Boot, which locks the L2 cache before booting Linux. At the moment it does not replace the Samsung bootloader, instead we let the original bootloader load U-Boot as an another (intermediate) bootloader. Another advantage of this is that U-Boot has proper device tree support, so we do not need to hardcode the kernel command line in the device tree.

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.
