mainlining shenanigans
Currently bcm2835_defconfig has CMA disabled which makes the
HDMI output on a Raspberry Pi 1 stop working during boot:
fb: switching to vc4drmfb from simple
Console: switching to colour dummy device 80x30
[drm] Initialized vc4 0.0.0 20140616 for soc:gpu on minor 0
[drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[drm] Driver supports precise vblank timestamp query.
vc4-drm soc:gpu: failed to allocate buffer with size 9216000
vc4-drm soc:gpu: Failed to set initial hw configuration.
So enable CMA and DMA_CMA in bcm2835_defconfig.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
