Preparations for Fermi DRAM clock changes
No, no, these will not implement Fermi reclocking. This set of patches
contains some of the preparatory work that I deem stable enough to
move upstream. Notable changes
- Training pattern upload routines from GK104+ now shared with GT215+
- Timing calculation for Fermi
- GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that
pesky GT 240.
- A routine to translate a VBIOS init

RESEND Preparations for Fermi DRAM clock changes
Two patches went missing as a result of PEBCAK. No v2 marks as nothing
changed really. Just resending for easier enforcement of patch order
in other people's trees. Sorry for the noise.
Original message:

Implement reclocking for DDR2, DDR3, GDDR3
Following a series of patches that implement memory reclocking for NVA3/5/8 with
DDR2, DDR3 and GDDR3 on board. I tested these patches on 6 different graphics
cards, but I expect reclocking now to work on many more.
Testers can pick up these patches and test it by enabling pstate
(nouveau.pstate=1). They should then be able to change clocks by writing to
/sys/class/drm/card0/device/pstate. Correct
