8cfbcbdb9c update platform code to use PALTemp Whami register to get cpu id
instead of reading register from tsunami chipset, saving an uncached

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.

ea03f8e35d Rather than using a loop to calculate the interrupt vector, use the ctlz instruction. 2004-06-06 19:33:50 -04:00

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

ce9b1a1e37 added some comments to palcode and zeroed system type in HWPRB (m5 will fill in)
console/console.c:
    0 the system type, let m5 overwrite
palcode/platform_m5.s:
    add some comments and make the timer interrupt actually care what CPU it happened on

4d3d5d7a3c Fix the sys_int_20 handler for doing low priority device interrupts.
Now reads the MISC register to handle interrupts from multiple CPUs

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

ae7e8a4660 makefiles updated to make use of cross compile tools
console/Makefile:
    All tools are variables now
palcode/Makefile:
    tool names changed to variables, can build palcode on zizzer

d7fba9784e The palcode will now build by simply typing make in this directory.
Most of the changes were to fix broken macros in platfrom_tlaser.s

palcode/Makefile:
    Completly new makefile to build palcode
palcode/ev5_alpha_defs.h:
    fixed a broken define
palcode/ev5_impure.h:
    macro fixes
palcode/platform_srcmax.s:
    manual macro expansion of broken macros... this file isn't needed to
    build tlaser palcode
palcode/platform_tlaser.s:
    lots of fixups to make the code assemble
