Add basic boot, setup and reset routines for LoongArch. Now, LoongArch machines use UEFI-based firmware. The firmware passes configuration information to the kernel via ACPI and DMI/SMBIOS. Currently an existing interface between the kernel and the bootloader is implemented. Kernel gets 2 values from the bootloader, passed in registers a0 and a1; a0 is an "EFI boot flag" distinguishing UEFI and non-UEFI firmware, while a1 is a pointer to an FDT with systable, memmap, cmdline and initrd information. The standard UEFI boot protocol (EFISTUB) will be added later.

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.
