SATA initialization order

I use a PowerQUICC II Pro processor and try to initialize the SATA controller. I'm a bit confused about two different statements in the manual (MPC8379E PowerQUICC™ II Pro Integrated Host Processor Family Reference Manual, Rev. 1).

  1. In chapter, the CHBA register is explained. The last sentence says, the content shouldn't changed after the controller is brought online.
  2. Chapter 16.7.2 describes the initialization steps. In step 1, we bring the controller online and in step 5 we write the CHBA register.

These chapters are contradictory, arn't they? Who is right?
