      Remove msic_dcr_read() in axon_msi.c · 2843e7f7
      Michael Ellerman authored
      
      
      msic_dcr_read() doesn't really do anything useful, just replace it with
      direct calls to dcr_read().

      Add dcr_host_t.base in dcr_read()/dcr_write() · 83f34df4
      Michael Ellerman authored
      
      
      Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we
      can save them the trouble and do it in dcr_read()/dcr_write().
      
      As some background to why we just went through all this jiggery-pokery,
      benh sayeth:
      
       Initially the goal of the dcr_read/dcr_write routines was to operate like
       mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx
       hardware, indirect DCR access is a pain (goes through a table of
       instructions) and it's useful to have the compiler resolve an absolute DCR
       inline.
      
       We decided that wasn't worth the API bastardisation since most places
       where absolute DCR values are used are low level 4xx-only code which may
       as well continue using mfdcr/mtdcr, while the new API is designed for
       device "instances" that can exist on 4xx and Axon type platforms and may
       be located at variable DCR offsets.
