copyright: update copyright on alpha system files

Fix bug in MDT BITMAP to allow more than 2GB of memory.

Signed-off by Ali Saidi <saidi@eecs.umich.edu>

fix Makefile for new source tree

update our copyrights to the new format

put panic instructions in palcode rather than looping on mchecks.

Add m5op to the build process
use quiesceNs on other CPUs
panic rather than spin on an error

console/Makefile:
Add m5op to the build process
console/dbmentry.S:
use quiesceNs on other CPUs
console/printf.c:
panic rather than spin on an error.

change from bootStrap* to using the cpuStack array for setting up
other processor stacks

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.

Merge zed.eecs.umich.edu:/.automount/fox/y/mserrano/alpha-system
into zed.eecs.umich.edu:/z/benash/bk/alpha-system

console/console.c:
Clean up code.
h/rpb.h:
Update CTB struct.

New console terminal block structure, fix kernel stack pointer.

console/console.c:
Use virtual addresses for kernel stack pointer, use new ctb structure.
h/rpb.h:
Update console terminal block structure.

changes

console/console.c:
fixed bootstrap stack
h/rpb.h:
ctb_term_type instead of ctb_baud

Add missing TSUNAMI ipi code.

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.)

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.

Add tlaser.h, required by platform.S

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
palcode/platform_m5.S:
Add support for tsunami with 64 processors

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.

Makefile cleanup, no seperate middle preprocessing steps anymore

cleanup makefile and fix platform bug introduced in last commit

palcode/Makefile:
Cleanup make file, no more ugly preprocessing steps
palcode/platform_m5.S:
fix a mistake with m5 platform cleanup from before

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

Fix from Adam: Strip the kseg off the physical address in the RPB structure.

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

changed to generate tlaser and tsunami console code at different
addresses so the uncachable bit is set for tsunami.

console/Makefile:
console/console.c:
changed to generate tlaser and tsunami console code at different addresses

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.

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

Rather than using a loop to calculate the interrupt vector, use the ctlz instruction.

Added ALPHA_ACCESS_BASE to get rid of machine_defs.h

erik and I made the the same modification... merged.

Major clean up of alpha system files.

console/Makefile:
palcode/Makefile:
moved header files to /h so updated make file for that
console/dbmentry.s:
console/paljtokern.s:
console/paljtoslave.s:
upadated to use osf file that the palcode uses, one less file

Deleted a whole bunch of files that we didn't nede in the header
directory

console/dbmentry.s:
console/printf.c:
removed unneeded includes

Setup makefile to compile the 3 flavors of palcode for each platform.

Add copy implementations to palcode.

palcode/osfpal.s:
Add copypal loop copy implementation.

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

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

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

Change addressing in interrupt code to meet physical addressing requirements

Fixed device I/O interrupt handling

Fix improper shift for loading address

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

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

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

Merge zizzer.eecs.umich.edu:/m5/Bitkeeper/alpha-system
into zizzer.eecs.umich.edu:/y/saidi/alpha-system

Added support for OPEN_CONSOLE and CLOSE_CONSOLE; fixed PUTS bug

Implement GetChar()

console/Makefile:
Quick install target to copy the binary to zizzer

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

Implement support for more console environment variables. There
are some default values here, but they can be changed from the
simulator itself. (Search in m5 for boot_osflags)

Get the console code to compile correctly
Add support for some thigns that M5 needs
Make this better support Tru64 v5.1

console/Makefile:
I couldn't figure out the old build system since I was missing
a bunch of tools at the time, so I kinda rewrote it.
console/console.c:
Get the includes right, and make things compile
little bit of cleanup along the way
console/paljtokern.s:
formatting junk
console/printf.c:
Formatting
get const right
h/lib.h:
fiddle with the includes that we need
console/console.c:
Get the BOOTDEVICE_NAME right
Add a bit of support for grabbing console environment variables
