Linux kernel source tree
13a0ea28e8
The function bootcmdline_init() in arch/mips/kernel/setup.c will populate the boot_command_line string using the parameters hardcoded in the kernel, and those provided in the devicetree file. Then, it would append the content of the arcs_cmdline variable, which is filled by the board's plat_mem_setup() function. The plat_mem_setup() function for the generic MIPS board would just copy the current boot_command_line to arcs_cmdline, which is nonsense for two reasons: - the result will be appended to the boot_command_line anyway, so all it does is duplicate every single parameter on the command line; - the code did not perform at all what it's supposed to, which is to retrieve the parameters passed by the bootloader. Fix this by calling fw_init_cmdline() in plat_mem_setup(), which will properly initialize arcs_cmdline to the parameters passed by the bootloader.

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.
