Ben Skeggs 8c3d3b385e drm/nouveau/bios: fix issue shadowing expansion ROMs
[ Upstream commit 402a89660e9dc880710b12773076a336c9dab3d7 ]

This issue has generally been covered up by the presence of additional
expansion ROMs after the ones we're interested in, with header fetches
of subsequent images loading enough of the ROM to hide the issue.

Noticed on GA102, which lacks a type 0x70 image compared to TU102,.

README

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.
