New Revision: 276739
URL: https://svnweb.freebsd.org/changeset/base/276739

Log:
  Add an APB base/size for the QCA955X for an upcoming QCA955x specific
  APB mux.
  
  It's larger than the AR71xx because it needs to replace the nexus
  for some devices (notably wifi) and the wifi driver (if_ath_ahb.c)
  reads the SPI data directly at early boot whilst it's memory mapped
  in.
  
  I'm eventually going to rip it out and replace it with a firmware
  interface similar to what exists for the if_ath_pci.c path -
  something early on (likely something new that I'll write) will
  suck in the calibration data into a firmware API blob and that'll
  be accessed from if_ath_ahb.c.
  
  But, one thing at a time.
  
  Tested:
  
  * QCA955x SoC, AP135 development board
