d375c80e7f Rework evbmips clock architecture to use common clock_subr.h routines. 
Additionally, do not fail if no RTC is present, as not all boards have one.

Malta now uses the common dev/ic/mc146818.c code as much as possible, reducing
local "custom" code.  These malta changes are *untested*, as I do not have
a Malta board to test with.  If someone would please test them and get back to
me, I'd appreciate it!

a86f56dbf6 Remove verbose debug message, and make sure we pass right IPL. 
(Pedantic, since IPL isn't used in ICU, but better to be pedantic and right
than wrong.)

5cd61be031 Add macros so that GPIOs can be accessed directly without having to use 
ioctls or the GPIO framework.  Useful for some subsystems such as PCMCIA, that
may also use GPIOs.  Requested by Kiyohara Takashi.

08f478e5ab Fix the RTC so that the AU1550 keeps accurate time. The RTC is taken from 
the TOY register, which is presumed to be seconds since Jan. 1 2000.

For now I'm assuming the trim divider is 32K, which makes 1 tick per sec.
This is true for the DBAU1550 board at least.  Other boards might need to
initialize a reasonable trim counter and establish the 32KHz oscillator.

In any case, this code is *no worse* on older systems than what was there
before.

7572f01aa0 Masking for mstart was still *not* right. This time I'm fairly sure I got 
it right -- OMSAL400 and MTX-1 boards should have functional PCI now.

ac76a40e3a Add Au1XXX PSC(Programable Serial Controller) bus-type driver. 
PSC supports four protocols (AC97, I2S, SPI, SMBus).
These protocol drivers will be configured on the bus.

6dd67e3239 Initial commit of aupcmcia chip driver. It requires board specific logic 
(coming in a the follow up commit for dbau1550 only), and is not yet complete.
It has serious problems, enough that it isn't yet usable, although the
functionality is all basically fleshed out.  It is not enabled in any
default kernels at this point, so it should be benign.  Hopefully the
bugs will soon be worked out and these caveats can be removed.

680d9eea68 - Don't expose dev_propdb directly -- provide devprop_*() wrappers instead. 
- Rework the ARMADILLO / epe device properties interaction so that it actually
  associates the MAC address property with the epe device instance.

e5312db1b0 Reenable PCI on DBAU1500. May still be useful for PIO devices. Comments 
in the config are left intact, though.
Add a PMAP-driven bus_space for access to upper memory, instead of using
wired entries.
Convert aupci to use said bus_space -- no measured performance impact.

07fe2e72a2 Add au_intr_enable() and au_intr_disable() API to allow for split interrupts 
(e.g. PCMCIA leaves GPIO interrupt masked and reenables them soft interrupt.)
Add checks for masked interrupts before calling the handler.
When removing last interrupt handler, mask off interrupts completely using
MASK_CLEAR and WAKEUP_CLEAR.  Tested on dbau1500.
