The "nomodeset" kernel cmdline parameter is handled by the vgacon driver
but the exported vgacon_text_force() symbol is only used by DRM drivers.
It makes much more sense for the parameter logic to be in the subsystem
of the drivers that are making use of it.
Let's move the vgacon_text_force() function and related logic to the DRM
subsystem. While doing that, rename it to drm_firmware_drivers_only() and
make it return true if "nomodeset" was used and false otherwise. This is
a better description of the condition that the drivers are testing for.

Add constants for the maximum size of the shadow-plane surface
size. Useful for shadow planes with virtual screen sizes. The
current sizes are 4096 scanlines with 4096 pixels each. This
seems reasonable for current hardware, but can be increased as
necessary.

Current (and older) Simics models for the Bochs VGA used the wrong PCI
vendor ID (0x4321 instead of 0x1234). Although this can hopefully be
fixed in the future, it is a problem for users of the current version,
not the least because to update the device ID the BIOS has to be
rebuilt in order to see BIOS output.

1234:1111 one.

We want to stop gup, which isn't the case if we use vmf_insert_page
and VM_MIXEDMAP, because that does not set pte_special.
The motivation here is to stop get_user_pages from working on buffer
object mmaps in general. Quoting some discussion with Thomas:

get_user_pages. It pins memory wherever it is, which badly wreaks at least
ttm and could also cause trouble with cma allocations. In both cases
becaue we can't move/reuse these pages anymore.
Now get_user_pages fails when the memory isn't considered "normal", like
with VM_PFNMAP and using vm_insert_pfn. For consistency across all dma-buf
I'm trying (together with Christian König) to roll this out everywhere,
for fewer surprises.
E.g. for 5.14 iirc we merged a patch to do the same for ttm, where it
closes an actual bug (ttm gets really badly confused when there's suddenly
pinned pages where it thought it can move them).
cma allcoations already use VM_PFNMAP (because that's what dma_mmap is
using underneath), as is anything that's using remap_pfn_range. Worst case
we have to revert this patch for shmem helpers if it breaks something, but
I hope that's not the case. On the ttm side we've also had some fallout
that we needed to paper over with clever tricks.
v2: With this shmem gem helpers now definitely need CONFIG_MMU (0day)
v3: add more depends on MMU. For usb drivers this is a bit awkward,
but really it's correct: To be able to provide a contig mapping of
buffers to userspace on !MMU platforms we'd need to use the cma
helpers for these drivers on those platforms. As-is this wont work.
Also not exactly sure why vm_insert_page doesn't go boom, because that
definitely wont fly in practice since the pages are non-contig to
begin with.
v4: Explain the entire motivation a lot more (Thomas)

The register_gop_device() function registers an "efi-framebuffer" platform
device to match against the efifb driver, to have an early framebuffer for
EFI platforms.
But there is already support to do exactly the same by the Generic System
Framebuffers (sysfb) driver. This used to be only for X86 but it has been
moved to drivers/firmware and could be reused by other architectures.
Also, besides supporting registering an "efi-framebuffer", this driver can
register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers
on non-X86 EFI platforms. For example, on aarch64 these drivers can only
be used with DT and doesn't have code to register a "simple-frambuffer"
platform device when booting with EFI.
For these reasons, let's remove the register_gop_device() duplicated code
and instead move the platform specific logic that's there to sysfb driver.

The bochs driver is only ~600 lines of code. Putting it into tiny/

and unneeded include statements were removed. No functional changes.

The drm_format_info() function returns NULL if the format is
unsupported, but the simplefb_get_validated_format() is expected to
return error pointers. If we propagate the NULL return then it will
lead to a NULL dereference in the callers. Swap the NULL and trade it
in for an ERR_PTR(-EINVAL).

driver before taking over the device.

The simpledrm driver is a DRM driver for simple-framebuffer framebuffers
as provided by the kernel's boot code. This driver enables basic
graphical output on many different graphics devices that are provided
by the platform (e.g., EFI, VESA, embedded framebuffers).
With the kernel's simple-framebuffer infrastructure, the kernel receives
a pre-configured framebuffer from the system (i.e., firmware, boot
loader). It creates a platform device to which simpledrm attaches.
The system's framebuffer consists of a memory range, size and format.
Based on these values, simpledrm creates a DRM devices. No actual
modesetting is possible.
A firmware framebuffer might also be specified via device-tree files. If
no device platform data is given, try the DT device node.
Make sure required hardware clocks and regulators are enabled while the
firmware framebuffer is in use. The basic code has been taken from the
simplefb driver and adapted to DRM. Clocks are released automatically
via devres helpers.
The drivers displays a console on simpledrm's framebuffer. The default
framebuffer format is being used.
v4:
* disable simplefb if simpledrm has been selected (Maxime)
v3:
* add disable function that clears screen to black (Daniel)
* set shadow buffering only for fbdev emulation
* set platform-driver data during device creation
v2:
* rename driver to simpledrm
* add dri-devel to MAINTAINERS entry
* put native format first in primary-plane format list (Daniel)
* inline simplekms_device_cleanup() (Daniel)
* use helpers for shadow-buffered planes
* fix whitespace errors
* add Device Tree match table
* clean-up parser wrappers
* use strscpy()

USB devices cannot perform DMA and hence have no dma_mask set in their
device structure. Therefore importing dmabuf into a USB-based driver
fails, which breaks joining and mirroring of display in X11.
For USB devices, pick the associated USB controller as attachment device.
This allows the DRM import helpers to perform the DMA setup. If the DMA
controller does not support DMA transfers, we're out of luck and cannot
import. Our current USB-based DRM drivers don't use DMA, so the actual
DMA device is not important.
Tested by joining/mirroring displays of udl and radeon under Gnome/X11.
v8:
* release dmadev if device initialization fails (Noralf)

v7:

* collapse USB helper into usb_intf_get_dma_device() (Alan)
* integrate Daniel's TODO statement (Daniel)
* fix typos (Greg)
v5:

* update SHMEM and CMA helpers for new PRIME callbacks

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.
Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.
v3:
* remove out-comented line in drm_gem_framebuffer_helper.h
(Maxime)
v2:
* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
