  /*
   * This is rather complicated for humans and ugly to verify, but for a machine
   * it's OK.  Still more as it is usually only applied to constants.  The upsides
   * on using this approach are:
   *
   *  - same mapping on all i.MX machines
   *  - works for assembler, too
   *  - no need to nurture #defines for virtual addresses
   *
   * The downside it, it's hard to verify (but I have a script for that).
   *
   * Obviously this needs to be injective for each SoC.  In general it maps the
   * whole address space to [0xf4000000, 0xf5ffffff].  So [0xf6000000,0xfeffffff]
   * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there).
   *
   * It applies the following mappings for the different SoCs:
