By calling uart_handle_break().  We'll still do the
"sun_do_break()" handling if the user gives two
breaks in a row.

We should probably do this in the other Sparc serial
drivers too.

Forgot to multiply by 8 * 1024, oops.  Correct the size constant when
the virtual-dma arena is 2GB in size, it should bet 256 not 128.

Finally, log some info about the TSB at probe time.

Until the uart is openned, port->info is NULL.

Also, init the port->irq properly and give a non-zero
port->membase so that the uart device reporting is done.

For SUN4V, we were clobbering %o5 to do the hypervisor call.
This clobbers the saved %pstate value and we end up writing
garbage into that register as a result.  Oops.

Use prom_startcpu_cpuid() on SUN4V instead of prom_startcpu().

We should really test for "SUNW,start-cpu-by-cpuid" presence
and use it if present even on SUN4U.

When crawling up the PCI bus chain, stop at the first node
that has an interrupt-map property before we hit the root.

Also, if we use a bus interrupt-{map,mask} do not forget to
update the 'intmask' pointer as we do for the 'intmap' pointer.

On SUN4V, force IRQ state to idle in enable_irq().  However,
I'm still not sure this is %100 correct.

Call add_interrupt_randomness() on SUN4V too.

On the PBM's first bus number, only allow device 0, function 0, to be
poked at with PCI config space accesses.

For some reason, this single device responds to all device numbers.

Also, reduce the verbiage of the debugging log printk's for PCI cfg
space accesses in the SUN4V PCI controller driver, so that it doesn't
overwhelm the slow SUN4V hypervisor console.

Add udelay to polling console write loop, and increment
the loop limit.

Name the device "ttyHV" and pass that to add_preferred_console()
when we're using hypervisor console.

Kill sunhv_console_setup(), it's empty.

Handle the case where we don't want to use hypervisor console.
