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.

The registers in question are for internal use and debug purposes.

These registers were present in the early revision of the DPAARM:
