The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

CONFIG_ACPI_VIDEO depends on more than just CONFIG_ACPI, so add those
dependencies to the Kconfig select condition. The case where some
dependencies fail to be satisfied should be handled correctly, because
in that case the ACPI_VIDEO symbols we use are converted into
static-inline stubs.

drm/nouveau: support fetching LVDS EDID from ACPI
Based on a patch from Matthew Garrett.

It doesn't seem to revert cleanly, but the problem lies in these
two config entries:
CONFIG_ACPI=y
CONFIG_ACPI_VIDEO=m
Adding a select for ACPI_VIDEO appears to be the best solution, and
is comparable to what is done in DRM_I915. Builds, boots, and appears to
work correctly.

sil164 transmitters are used for DVI outputs on Intel/nvidia and ATI setups.
So far only nouveau can use this driver.

Now that highlevel DRM no longer requires PCI, we can move the requirement
into the lowlevel drivers.

This partially reverts e4b41066, as this driver is intended to be
useful with any KMS driver for suitable hardware. The missing build
dependency that commit workarounded was DRM_KMS_HELPER.

The ch7006 driver could be built even when nouveau was not enabled,
but the build fails in that case, so make it depend on DRM_NOUVEUA.
Also make the I2c encoder/helper chips menu depend on I2C (no build
error, just visual inspection).

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.
This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.
This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
