^~~~~~~~~~~~~~~~~~~~~~~~~
A couple of issues here. Firstly we already have a bootinfo.h that has a
prototype for process_uboot_commandline(), we should include that.
Secondly uboot_kbd is not used at all and can be removed. Thirdly the
conditional code based on CONFIG_BLK_DEV_INITRD means that sometimes
uboot_initrd_start and uboot_initrd_end are not needed. Make their
declaration and asignment conditional on CONFIG_BLK_DEV_INITRD same as
the code that uses them.

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.
