Add 64-bit Block Move support (Direct & Table Indirect) (Ryan Harper)

This patch adds support for 64-bit Block Move instructions.  There are multiple
modes for 64-bit Block moves, direct, indirect, and table indirect.  This patch
implements Direct and Table indirect moves which are needed by 64-bit windows
and SYM_CONF_DMA_ADDRESSING_MODE=2 for the Linux sym53c8xx_2 driver respectively.

Two helper functions are included to check which mode the guest is using.  For
 64-bit direct moves, we fetch a 3rd DWORD and store the value in the DBMS
register.  For Table Indirect moves, we look into the table for which register
contains the upper 32-bits of the 64-bit address.  This selector value indicates
which register to pull the value from and into dnad64 register.

Finally, lsi_do_dma is updated to use the approriate register to build a 64-bit
DMA address if required.

With this patch, Windows XP x64, 2003 SP2 x64, can now install to scsi devices.
Linux SYM_CONF_DMA_ADDRESSING_MODE=2 need a quirk fixup in Patch 4 to function
properly.

Current implementation of memory-mapped i8042 controller is atm
implemented with an interface shift (it_shift) parameter, like most all
memory-mapped devices in Qemu.
However, this isn't suitable for MIPS Magnum, where i8042 controller is at
0x80005000 up to 0x80005fff.

Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real
machine, and found that odd addresses are for status/command register, and
even addresses for data register.

Attached patch implements this behaviour by replacing the it_shift
parameter by a mask one.
Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042
controller at 0x80005060 and 0x80005061.

R2D evaluation board uses SCI for SPI connection.  So, Linux kernel for R2D with

This patch avoids it and reduces the kernel config modification work for QEMU.

SH4: Implement FD bit

SH4 manual say that if a floating point instruction is executed while
FD bit in the status register is 1, an exception should be raised. QEMU
presently does not do that, so the kernel does not initialize FP state
for any thread, nor does it save/restore FP state. The most apparent
consequence is that while recent gcc/libc expect double-precision mode
to be set by kernel, they run in single-precision mode, and all FP code
produces wrong values.

This patch fixes this. It also fixes a couple of places where PC was
not updated before handling an exception, although both those places
deal with invalid instruction and don't lead to any user-visible bugs.

LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)

Basically after each DMA transfer the Openserver driver would issue an
empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no
second DWORD and therefore the DSP should only be incremented by 4 bytes
instead of the 8 bytes we currently do.

Here's a snippet of the log:

lsi_scsi: Data ready tag=0x100d9 len=16384
...
lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000
lsi_scsi: DMA addr=0x07a09000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400
lsi_scsi: Wrong phase got 1 expected 0

Note the 2nd DWORD after the empty opcode; the next opcode in the DMA
transfer sequence. As can be expected the address after that has the next
DMA address to use.

After the attached patch the DMA transfer is able to complete successfully:

lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a0d000
lsi_scsi: DMA addr=0x07a0d000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e5c opcode 01000400 arg 07a0d400
lsi_scsi: DMA addr=0x07a0d400 len=1024
...

Tested againsted Openserver 5.0.5 and Debian ARM.
