c3d47c1de8 Fix console to work on all systems.
console/console.c:
    CONS_REM (remote console) doesn't work on Tru64.  Use CONS_DZ which
    seems to work alright everywhere.

fce2978d41 console code cleanup
console/console.c:
    the go parameter to unixBoot is never used, so get rid of it.
    just panic if we return from unixBoot since it's never supposed
    to happen.
    remove the MAX_CPUS parameter and the bootStrapImpure variable
    and just allocate memory as needed.  (Can in theory support many
    more CPUs.)

941db36a67 pass the location of the m5 backdoor via the m5AlphaAccess variable
only compile one console

console/Makefile:
    Now that the location of the m5 backdoor is passed into the
    console via the m5AlphaAccess variable, we only need to
    compile one console, and don't need to define TLASER or TSUNAMI
console/console.c:
    Don't hardcode the location of the AlphaAccess structure, but
    rely on m5 to pass in the correct value.
    Setup "volatile struct AlphaAccess *m5AlphaAccess" for use and
    get rid of the hardcoded usage.

5821f37cb6 Add support for tsunami with 64 processors and fix some console bugs
I steped on while doing it

console/console.c:
    Allocate more HWRPB pages so we have room for 64 percpu_rpbs
    Fix writing of Console Relocation Block virtual addresses so that
    if they are outside of the first page, which they will be with more
    than 8 processors, the correct adress is written
palcode/Makefile:
    Update makefile for tsunami with 64 processors

99a522fb8b do a better job of always locking printf. We used to only lock on
secondary cpus, this also locks on the primary cpu.
Now the initial print out doesn't get garbled with more than 1 cpu.

1940fcdd29 changes to make smp work in linux
console/console.c:
    Remove Printed SimOS references and replace with M5
    Rework the SMP stuff, so we don't trash any stacks, or what we
    thought were stacks, but are actually other ppls memory.
console/dbmentry.s:
    add a carefully crafted piece of assembly that doesn't use the stack,
    so we don't clobber anthing in the time between when we are spinning
    and when the OS tells us to go.
palcode/platform_m5.s:
    add/fix code for IPI, multiprocessor interrupts (DIR), and initial
    bootstrapping of the cpu

ae3ba61665 changed the code not to use r11 (specifically) and r8,r9 for good
measure. The rest of the registers I used are touched by the tlaser
platform code so I would guess their are fair game.
Random memory troubles hopefully over.

ad63f2e67e Copy variables over one at a time rather than copying 4 bytes at a
time. Easiest way to deal with the endian issue.

31ac4ce140 console code now builds on zizzer
console/Makefile:
    Updated to build on linux and removed
    lots of crud that compiled, disassembled, and then reassembled
console/dbmentry.s:
    the assembler didn't like they comments, so I removed them
console/printf.c:
    Gcc was very unhappy, so I fixed this line
h/lib.h:
    time_t is defined in a std header, and this was causing some problems

b582b5058e palcode updated to deal with interrupts correctly
deleted and then upon realizing we needed them undeleted a bunch of
header files in the palcode dir

console/Makefile:
    fixed so it will work with tru64... still haven't got the console to build under linux
palcode/platform_m5.s:
    fixed code to "fake" srm console interrupt handling correctly
    include serial interrupts

5d3149b69d Added platfrom_m5 - Our hacked up tsunami palcode and modified palcode
makefile to that end. Additionally made a change in console to
preserve t7 on call back because linux uses it for the "current"
pointer.

console/Makefile:
    Changed makefile back to using gcc and gas rather then trying to
    cross-compile for now
console/console.c:
    Put code in to save t7 on CallBackFixup() call and changed the
    system type to Tsunami
palcode/Makefile:
    updated palcode makefile to have targets for tlaser and tsunami
