6b7ba54456 Initial support for Freescale PowerQUICC III MPC85xx system-on-chip family. 
The PQ3 is a high performance integrated communications processing system
based on the e500 core, which is an embedded RISC processor that implements
the 32-bit Book E definition of the PowerPC architecture. For details refer
to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E

This port was tested and successfully run on the following members of the PQ3
family: MPC8533, MPC8541, MPC8548, MPC8555.

The following major integrated peripherals are supported:

  * On-chip peripherals bus
  * OpenPIC interrupt controller
  * UART
  * Ethernet (TSEC)
  * Host/PCI bridge
  * QUICC engine (SCC functionality)

This commit brings the main functionality and will be followed by individual
drivers that are logically separate from this base.

5d8dd7e60b Rename OEA to AIM. The former means nothing as it applies to all 
processors (it's the PowerPC Operating Environment Architecture).
AIM designates the processors made by the Apple-IBM-Motorola
alliance and those we typically support.

While here, remove the NetBSD option IPKDB. It's not an option
used by us. Also, PPC_HAVE_FPU is not used by us either. Remove
that too.

c31c26450b Not all cpus are MPC750s. Replace the MPC750 cpu option with OEA. This 
stands for Operating Environment Architecture and is the specification that
all of the MPC6xx, MPC7xx, MPC7xxx and IBM7xx CPUs adhere to.

5f07565bcb Move SHOW_BUSYBUFS and PANIC_REBOOT_WAIT_TIME into the MI options file, since 
MI code uses them, and every platform provides them (except x86_64 whose
options file was lacking one).

98f8e6c099 Driver for the Apple UniNorth Host-PCI bridge. 
This is in a PowerMac-specific subdirectory as it is hoped that we will support
more than just the PowerMac platform.
