The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

Some drivers can be built on more platforms than they run on. This is
a burden for users and distributors who package a kernel. They have to
manually deselect some (for them useless) drivers when updating their
configs via oldconfig. And yet, sometimes it is even impossible to
disable the drivers without patching the kernel.
Introduce a new config option COMPILE_TEST and make all those drivers
to depend on the platform they run on, or on the COMPILE_TEST option.
Now, when users/distributors choose COMPILE_TEST=n they will not have
the drivers in their allmodconfig setups, but developers still can
compile-test them with COMPILE_TEST=y.
Now the drivers where we use this new option:
* PTP_1588_CLOCK_PCH: The PCH EG20T is only compatible with Intel Atom
processors so it should depend on x86.
* FB_GEODE: Geode is 32-bit only so only enable it for X86_32.
* USB_CHIPIDEA_IMX: The OF_DEVICE dependency will be met on powerpc
systems -- which do not actually support the hardware via that
method.
* INTEL_MID_PTI: It is specific to the Penwell type of Intel Atom
device.
[v2]
* remove EXPERT dependency
[gregkh - remove chipidea portion, as it's incorrect, and also doesn't
apply to my driver-core tree]

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

Use a command line option (vram) rather than hardcoding the vram size. LxFB
already does this; it's useful for machines that can't query the BIOS for fb
size. This patch originated from David Woodhouse, was modified by Jordan
Crouse, and was then modified further by me.
This also adds some gxfb documentation in Documentation/fb.

We cannot assume that the BIOS will be correctly setting up the hardware, so
set some bits in various display registers to enable video output. Allow an
advanced user to specify a frambuffer size, rather then probing the BIOS. All
of these fixes were prompted by the OLPC effort.

A framebuffer driver for the display controller in AMD Geode GX processors
(Geode GX533, Geode GX500 etc.). Tested at 640x480, 800x600, 1024x768 and
1280x1024 at 8, 16, and 24 bpp with both CRT and TFT. No accelerated features
currently implemented and compression remains disabled.
This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS)
has created an appropriate virtual PCI header.

According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant. The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.
Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank. For drivers that do, they can fill up this field with their own
version.
The end result is a smaller code size. And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

Geode framebuffer driver updates:
- Local mode list (taken from modedb.c) containing only relevant modes.
This also makes the driver work as a module.
- Make it a PCI driver (from James Simmons <jsimmons@infradead.org>).
- A few other minor cosmetic bits and pieces.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
