commit fe82de91af83a9212b6c704b1ce6cf6d129a108b upstream.
This reverts commit d9df9fb901d25b941ab2cfb5b570d91fb2abf7a3.
For the OCTEON boards, it need to patch the built-in DTB before using
it. Previously it judges if it is a built-in DTB by checking
fw_passed_dtb. But after commit 37e5c69ffd41 ("MIPS: head.S: Init
fw_passed_dtb to builtin DTB", the fw_passed_dtb is initialized even
when using built-in DTB. This causes the OCTEON boards boot broken due
to an unpatched built-in DTB is used. Revert the commit d9df9fb901d2 to
restore the codes before the fw_passed_dtb is used and then fix this
issue.
Fixed: 37e5c69ffd41 ("MIPS: head.S: Init fw_passed_dtb to builtin DTB")

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.
