matt bc49a6eede Fix long time codegen bug. Only the COMPARE, ADD, MINUS operations actually 
set the C(arry) bit appropriately.  All other leave it in an indeterminate
(to GCC) state.  Mark that by setting CC_NO_OVERFLOW.  Change vax.md emission
of branches that use the C bit to use OUTPUT_JUMP so that if CC_NO_OVERFLOW is
set, branches that would normally use the C bit use opcodes that don't use the
C bit (jgtru -> jneq && jlssu -> jeql).  Delete the cmpdi pattern.

thorpej c39065eb62 Add support for running directly out of flash: 
* Require that the builder Makefile provide a linker script.
* After making sure the MMU is disabled, check to see if
  _etext == __data_start.  If not, then copy the .data contents
  into RAM.
* Put the stack in .bss.

thorpej 87de164ab4 Fix a silly bug in the propellor spinning code. 2002-02-23 17:25:32 +00:00
scw c4dbe1a160 Allow MD code to provide functions for reading/writing NVRAM/RTC 
locations. If passed NULL, the old behaviour using bus_space_{read,write}_1()
is used. Otherwise, all access to the chip goes via the MD functions.

This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is not
directly addressable.

toshii 3676484136 Make KERNEL_VM_SIZE a little larger so that ubc_init doesn't fail from 
ENOMEM.

dbj c467951c58 turn on polling using cnpollc 2002-02-23 10:51:50 +00:00
dbj b97918f553 In adb_soft_intr, remove the packet from the queue before calling the 
completion routine so that the completion routine can reentrantly
process the queue.  This happens, for example. when polling is turned
on by entering the debugger by keystroke.

martin a290138790 Add more examples. 2002-02-23 08:11:22 +00:00
thorpej d114b32f24 Add some nops after we enable the MMU, for good measure (enough for 
the nops to be the prefetch'd insns when the MMU switch occurs).
 2002-02-23 05:58:46 +00:00
thorpej f31f6affa9 Make sure the MMU is enabled after we switch to the new kernel 
page tables (gzboot disables the MMU before it does its work).
 2002-02-23 05:55:26 +00:00
thorpej 0b91bc440f Move files[] from open.c to globals.c, so that it's possible to 
use libsa in an application where there are no file systems or
devices.
 2002-02-23 05:44:24 +00:00
thorpej 0fac1c42e9 gzboot -- boot a gzip'd kernel image. This is useful for booting 
compressed kernel images from flash.

This needs more work, but is a good first-pass.
 2002-02-23 05:41:14 +00:00
thorpej 1152fa21da Add some simple standalone device drivers for IOP310-based boards. 2002-02-23 05:12:01 +00:00
thorpej 2365d7ec78 Add a '-s' option which will cause mdsetimage to write back the 
actual image size copied back into the kernel.

martin 8af2b425a2 Add a missing call to isapnp_config(). 
Do not hardcode IST_EDGE, use the type from the attach args.

Noticed by Christos Zoulas.

 + PCLOCK estimation.
 + remove duplicated code.

kleink 3ca01a7f77 Do without stfiwx; per PEM32 Rev. 1 it's an optional part of the UISA, 
and not implemented on the 601.

thorpej 37595cfcf8 Fix the "va" argument to pmap_map_entry() when mapping kernel_ptpt. 
This happened to work in the IOP310 because the kernel runs VA==PA.

ad 5fcb6944f5 - Make stic0 as part of wscons. 
- Remove wsmouse0/wskbd0 from all, since it already calls MAKEDEV wscons.

matthias 21fb786623 Declare the global register variable kps_strings before including anything 
as this needs to be done before any function is defined (and there seems
to be a function definition in one of the include files).
