This patch series adds speedo identification functionality for tegra
T20 and T30. It reads speedo value from fuse and chooses CPU and core 
process ID by checking speedo corner tables.

V2:
* Split spare fuse related changes to a separate patch
* Keep original fuse init flow on an unknown chip
* Change size check of speedo cornor table
* Set speedo id to 0 with unknown chip revision/SKU
* Set process id to 0 when speedo value out of range

  ARM: tegra: Add speedo-based process identification
  ARM: tegra: T30 speedo-based process identification
