definitions.
* Include <mips/cpuregs.h> in <cpu.h> so kern_clock.c has user/kernel
status bits in scope. Still needs work; r2k/r4k previous-mode bits
are different.
* Include <mips/mips_param.h> in pica/include/param.h, for locore declarations,
and definitions of vm and other constants that should be shared across
NetBSD/mips systems to esnsure user-level binary compatibility.
* include <mips/locore.h> where callbacks into locore are made, to get
prototypes in scope. Cast calls appropriately.
* include <mips/cpuregs.h>, not the old Sprite-derived <machine/machConst.h>.
machConst.h is deprecated.
* dk_establish() must return void, not int.
* Make S expand to an absolute path at compile time.
* Use `-S' rather than `-x' to remove debugging symbols.
* Garbage collect unused variables.
* Reverse a handful of port-specific changes that do not correspond to
the common build model and are not needed.
a boot string for firmware that can do this, such as the SPARC and
the sun3 models. It is currently silently ignored on all other
hardware now, however. The MD function "boot()" has been changed to
also take a char *.
mapping code. (instead of using a "slot" and multiplying by 4 and adding the
pin number later to get the IRQ, just use base IRQ value and add the pin
number.)
comment immediately preceding it: We have to take the most significant
"numbits" from the returned value "ph", and the rest from our addr. The
addition used previously introduced a carry which was causing great
difficulty in determining the correct PA of the framebuffer VA passed in
by the booter.
occupy a slot. This is necessary so that GRFIOCMAP can find the correct
physical address of the framebuffer. Fixes P550, some LC models, and
perhaps the PB520.
a serial console and the PRAM read/write code happens to use the ADB ROM
vectors, we will have problems because the ADB hasn't been initialized.
For now, the only class of machines that we will set these up on regardless
of whether we are on a serial console or not is the original II series (II,
IIx, and IIcx). Others can come later.
Don't manipulate the memlist passed from the kickstart rom + bootloader, as
we want it unchanged in case we boot via /dev/reload.
Instead, make z2mem_start known to pmap.c; and use int in pmap_bootstrap to
detect the right segment to correct and the amount.
XXX The transformation of z2mem from physical to virtual kernel addresses
in amiga_init.c must not be done before the pmap_bootstrap() call now!
message-in. The remaining transfer count restored when a device is
reselected needs to be saved. The saved value is needed to compute
the number of bytes transferred if another disconnect occurs. This
fixes a random read data corruption that occurs on certain disks that
may disconnect more than once in the middle of a DMA transfer.
