thorpej d1b4b49231 - Use PALcode ops names defined in <machine/pal.h>. 
- Fix a few bugs in the software single-stepping support code, where
  VMS PALcode ops were being checked, rather than OSF/1 PALcode ops,
  causing erroneous results in the "exception return" and "unconditional
  branch" predicates.
- Add the BWX instructions ("ldbu", "ldwu", "stb", "stw") to the
  "load" and "store" predicates.

thorpej a14bab3438 Don't define another copy of the PALcode ops here; direct readers to 
<machine/pal.h>.

scottr 19e555febb Check booter flags for a bit that tells us whether we should construct 
bootdev from the SCSI ID passed in via the Booter's environment.
(Does the right thing for older versions of the Booter.)

thorpej 4fe999c6bf - Add the "amask" and "implver" operate subfunctions.

thorpej d1fbc82e28 From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition": 
An IMB intruction must be executed after software or I/O devices
	write into the instruction stream or modify the instruction
	stream virtual address mapping, and before the new value is
	fetched as an instruction.

We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

thorpej 37b8edbeac In addition to MAS_ABT, check TAR_ABT when doing configuration space 
reads.  This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts.  Reported by Matthias Drochner.
