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
