Missing FMAN QMI registers from Documentation

I am trying to understand how the FMAN Ethernet code works in u-boot for the T1024 processor.  I am using the following documentation: QorIQ T1024 Data Path Acceleration Architecture (DPAA) Reference Manual, rev. 0.  In u-boot they are referencing registers that do not appear in the documentation.  Specifically in the FMAN QMI memory block, u-boot is updating FMQM_IEN (0x418) and FMQM_IE (0x414).  I have looked at most of the code and noticed that sometimes bit definitions have changed within some registers.

The document I am using is the latest.  I was wondering if those register actually exist, or is u-boot not up to date with the register definitions?

 

Thank you for your help.
