5f1c88d70d Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete. 2005-12-24 20:06:46 +00:00

c9d34b2987 Add an offset to the I/O port translations. This allows IQ80321 
and others to avoid providing PCI I/O space at address 0.
Iyonix, however, needs to provide PCI I/O space at 0.
The others require I/O space to be offset in part due to a bug
work-around in wm(4) which requires that I/O space access be used
to reset the controllers.  If I/O space is mapped at zero, the card
claims, but ignores, the transactions, and the controller doesn't
get reset properly and can't then be used.

6b2d8b66a4 merge yamt-km branch. 
- don't use managed mappings/backing objects for wired memory allocations.
  save some resources like pv_entry.  also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.

06ea4a681d Don't assume that we are the PCI host. Actually check, and make sure that 
we set things up so that we can run either as a PCI host or as a PCI slave
(working within the PCI BARs that the system BIOS has configured for us).

87d5bba5b3 Replace the ad-hoc "section mapping table" for static device mappings 
with a more generic "devmap" structure that can also handle mappings
made with large and small pages.  Add new pmap routines to enter these
mappings during bootstrap (and "remember" the devmap), and routines to
look up the static mappings once the kernel is running.

bbba90a2fb Don't expose KERNEL_TEXT_BASE outside of board-specific code. This gives 
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

d599df9587 Continue the " - . - 8" purge. Specifically: 
add	rd, pc, #foo - . - 8		->	adr	rd, foo
ldr	rd, [pc, #foo - . - 8]		->	ldr	rd, foo

Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.

Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

1a5a7fe7b7 Use indirect configuration for on-board devices (i.e. those things 
attached to "obio") on the IQ80310 and IQ80321.  It makes more sense
to do it this way for this type of system (the goal being to encapsulate
as much information about the board as possible into one file).

d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries, 
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.
