figure out how the interrupt was routed from xbridge to xheart... (it bypasses
the regular `have xbridge send a xio interrupt packet' mechanism)

specified in the kernel configuration file, but is provided by macebus(4)
as part of the child device attachment args, and provide both crime and
mace interrupt bitmasks; this allows us to only really enable interrupt
sources we care about, and to avoid invoking interrupt handler we don't need
to for the few mace interrupts multiplexed at the crime level.

on all systems but O2 (to catch up soon). Also use the IOC4 MCR register to
figure out the IOC4 clock, instead of checking the widget control register,
to be consistent with iof(4).

return zero on success and nonzero on failure.
This commit only performs mechanical changes for the existing emulops to
always return zero.

Origin 350 and Tezro systems. While this chip provides serial ports, an ATAPI
interface and a PS/2 keyboard and mouse interface, this code currently only
attempts to support the serial ports.

some years ago for KL enumeration, building on the existing XBow support
to limit ourselves to a single node for now.
This is a work-in-progress; it currently lacks complete interrupt code,
as well as PCI resource management. And there are likely bugs creeping
inside.

This should take care of the simpler ones (i.e., timeout values of

Move calling ether_ioctl() from the top of the ioctl function, which
at the moment does absolutely nothing, to the default switch case.
Thus allowing drivers to define their own ioctl handlers and then
falling back on ether_ioctl(). The only functional change this results
in at the moment is having all Ethernet drivers returning the proper
errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown
ioctl's.

use, plus we leave DMA enabled when rebooting. This leads to an interrupt
storm at boot time if we were receiving/transmitting network traffic whilst

- Internal restructure to separate code paths.
- Add support for early console. This allows for gbe(4) to takeover were
the ARCBios leaves off (if we should do so).
- Add support for 8bpp and 16bpp colour depths. As a result, we also have
support for colourmaps. We now use 8bpp as the default.
- Add mmap() support, enabling wsfb to operate correctly.
- Correct initial origin problem that occurred occasionally.
