The Qemu platform was originally implemented to have an easily supportable
platform until Qemu reaches a state where it emulates a real world system.
Since the latest release Qemu is capable of emulating the MIPSsim and
Malta platforms, so this goal has been reached.  The Qemu plaform is also
rather underfeatured so less useful than a Malta emulation.

A raw binary boots about twice as fast as SREC.

The possibility to generate SREC binaries remains by simply using the
vmlinux.srec target but seems only useful for the probably hypothetical
case where one of these systems is booted over a serial interface.

- EISA support for non PCI RMs (RM200 and RM400-xxx). The major part
  is the splitting of the EISA and onboard ISA of the RM200, which
  makes the EISA bus on the RM200 look like on other RMs.
- 64bit kernel support
- system type detection is now common for big and little endian
- moved sniprom code to arch/mips/fw
- added call_o32 function to arch/mips/fw/lib, which uses a private
  stack for calling prom functions
- fix problem with ISA interrupts, which makes using PIT clockevent
  possible

This patch adds IDs for new Au1200 variants: Au1210 and Au1250.
They are essentially identical to the Au1200 except for the Au1210
which has a different SoC-ID in the PRId register [bits 31:24].
The Au1250 is a "Au1200 V0.2".

These symbols appear in oprofile output, stacktraces and similar but only
make the output harder to read.  Many identical symbol names such as
"both_aligned" were also being used in multiple source files making it
impossible to see which file actually was meant.  So let's get rid of them.
