Whether xtensa cores start from primary or secondary reset vector is configurable and may be chosen by board designer or controlled at runtime. When secondary reset vector is unused its location in memory may not be writable. Make secondary reset vector support conditional and don't build and load secondary reset vector code when it is disabled. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
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.
