  ICC is divided into 4 modules:
  - IccOverClocking: the overclocking library, distributed as binary,
  - IccSetup: code linked with setup browser; supports overclocking and uses overclocking lib
  - IccPlatform: not linked with setup, supports all Icc features except overclocking; does not use overclocking lib
  No part of ICC belongs to BIOS Reference Code.

  IccPlatform disables unused PCI/PCIe clocks and transfers data from MBP to Icc Setup
