25d056473c Clean up kernel initialization. Use the bootinfo structure (or innate 
knowledge) earlier, and gather all information needed earlier.  Mark the
init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc.  Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).

bd60d9c62d Rewrite the way the platform model string is determined: 
- Attempt to find the model string in the HWRPB's DSR area.  Failing that
  (if the HWRPB version is too old)...
- Look up the system variation in a variation/string table.  Failing that
  (unknown variation)...
- Create a default model string using the variation number.

Also, factor out a bunch of common code.

7fbc685c06 Make it a little more clear that the "eb164" systype doens't necessarily 
mean that a machine is a DEC EB164 (it may be an AlphaPC 164, which is
different, from the firmware's perspective).

314f40f8d8 We can't count on the CIA revision register telling us if we're a 21171 
or 21172, so make the chip/revsion output a little more sane.

change its type from a pointer to a never-defined structure to a
u_int64_t.

92d17b5b50 clean up the way bootinfo information is passed and used: move the version 
number passed by the boot block into a register, change the kernel's
bootinfo handing so that it always uses bootinfo to get bootinfo-ish values
(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.
