Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and
make it a device_t. Upcoming functional changes will require the
device_t associated with a TODR device.

Change todr_chip_handle::bus_cookie -> todr_chip_handle::todr_devaux.
Nothing was using the old field, but I decided to keep it around just
in cause something needs it in the future.

And with these largely mechanical yet semantically meaningful changes,
thus spake the Oracle: "Welcome to NetBSD 11.99.2."

Typo correction: it's isa_dmadestroy(), not isa_dma_destroy(), apparently.

isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.

the ISA bus and devices attaching to the ISA bus"). Define
isa_detach_hook() in MD ISA implementations. Define isa_dmadestroy().

Rename IPL_IMP -> IPL_VM.

Add __KERNEL_RCSID tags to footbridge files.

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

branches: 1.1.2; 1.1.4; 1.1.6;
Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

Use PAGE_SIZE rather than NBPG.

Add __KERNEL_RCSID tags to footbridge files.

Use separate function pointers for dmamap_sync pre- vs post- operations.
Change the bus_dmamap_sync() macro to test the ops argument against pre-
and post- constants. The compiler will optimize out dead code because
of the constants. Since post- operations are not needed on ARM (except
for ISA bounce buffers), this eliminate a large number of function calls
which are noops, each of which cost at least 6 cycles just in the call
and return overhead (not to mention whatever other useless work the
compiler decides to do in the callee).

Overhaul how DMA ranges work in the ARM bus_dma implementation.

A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length. In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
