drm/nouveau: teach nouveau_bo_pin() how to force a contig vram allocation
We have the ability to move buffers around in the kernel if necessary,
and should probably use it rather than failing if userspace passes us
a non-contig buffer for a plane.
The NOUVEAU_GEM_TILE_NONCONTIG flag from userspace will become a mere
initial placement hint once all the relevant paths have been updated.

drm/nouveau/bios: translate ramcfg strap through M0203
A machine has been spotted where the ramcfg strap is "8", and the ramcfg
xlat table goes 0-7,0-7, resulting in us selecting config 0 for memory
items. On this particular system, config "8" is available and supposed
to be used. It appears that starting from GT21x (where Mv2 appears),
we're supposed to use the value in this table instead.
One concern here is that not all the places we currently use ramcfg xlat

On architectures for which access to GPU memory is non-coherent,

drm: Decouple EDID parsing from I2C adapter
The drm_get_edid() function performs direct I2C accesses to read EDID
blocks, assuming that the monitor DDC interface is directly connected to
the I2C bus. It can't thus be used with HDMI encoders that control the
DDC bus and expose EDID blocks through a different interface.
Refactor drm_do_get_edid() to take a block read callback function
instead of an I2C adapter, and export it for direct use by drivers.
As in the general case the DDC bus is accessible by the kernel at the
I2C level, drivers must make all reasonable efforts to expose it as an
I2C adapter and use drm_get_edid() instead of abusing this function.

DRM slave encoders require their associated struct drm_encoder instance

driver will need to either create drm_slave_encoder instances that fake
