This replaces all the pll_types definitions for ones that match the types
used in the tables in recent VBIOS versions.
get_pll_limits() will now accept either type or register value as input
across all limits table versions, and will store the actual register ID
that a PLL type refers to in the returned structure.

sil164 and friends are the most common, usually they just need to be

There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:
<darktama> it's not worth limiting the quirk to just where we know it can
work? i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC

On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.
This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets. The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.

We just need to clear the SBA and ENABLE bits to reset the AGP
controller: If the AGP bridge was configured to use "fast writes",
clearing the FW bit would break the subsequent MMIO writes and
eventually end with a lockup.
Note that all the BIOSes I've seen do the same as we did (it works for
them because they don't use MMIO), OTOH the blob leaves FW untouched.

We totally fail at detecting un-POSTed chipsets prior to G80. This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.
NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

The connector table index in the DCB entry for each output type is an

still use it to prevent creating multiple TV connectors.

Apparently the original reason for checking this was there were known
register accesses that caused hangs on some chipsets. This was more
than likely because of incorrect parsing of previous opcodes, and I
hardly think aborting a script half way through is going to be any
better (in fact, we have had bug reports where this has been the cause
of s/r failures among other things).
This patch (which has been in Fedora 12 for a long time now) removes
all checking for known register ranges, and just leaves the check to
ensure the access is within the mapped aperture to avoid an oops.

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.
