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:
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
