Section 10.3 of the Hexagon V73 Programmer's Reference Manual
A duplex is encoded as a 32-bit instruction with bits [15:14] set to 00.
The sub-instructions that comprise a duplex are encoded as 13-bit fields
in the duplex.
Create a decoder for each subinstruction class (a, l1, l2, s1, s2).
Extend gen_trans_funcs.py to handle all instructions rather than
filter by instruction class.
There is a g_assert_not_reached() in decode_insns() in decode.c to
verify we never try to use the old decoder on 16-bit instructions.

The Decodetree Specification can be found here
https://www.qemu.org/docs/master/devel/decodetree.html
Covers all 32-bit instructions, including HVX
We generate separate decoders for each instruction class. The reason
will be more apparent in the next patch in this series.
We add 2 new scripts
gen_decodetree.py Generate the input to decodetree.py
gen_trans_funcs.py Generate the trans_* functions used by the
output of decodetree.py
Since the functions generated by decodetree.py take DisasContext * as an
argument, we add the argument to a couple of functions that didn't need
it previously. We also set the insn field in DisasContext during decode
because it is used by the trans_* functions.

The generators are generally a bunch of Python if-then-else
statements based on the regtype and regid. Encapsulate regtype/regid
into a class hierarchy. Clients lookup the register and invoke
methods.
This has several advantages for making the code easier to read,
understand, and maintain
- The class name makes it more clear what the operand does
- All the methods for a given type of operand are together
- Don't need hex_common.bad_register
If a regtype/regid is missing, the lookup in hex_common.get_register
will fail
- We can remove the functions in hex_common that use regtype/regid
(e.g., is_read)
This patch creates the class hierarchy in hex_common and converts
gen_tcg_funcs.py. The other scripts will be converted in subsequent
patches in this series.

Currently, the register number (MuN) for modifier registers is the
modifier register number rather than the index into hex_gpr. This
patch changes MuN to the hex_gpr index, which is consistent with
the handling of control registers.
Note that HELPER(fcircadd) needs the CS register corresponding to the
modifier register specified in the instruction. We create a TCGv
variable "CS" to hold the value to pass to the helper.

The current logic does not check for this condition, resulting in
the incorrect assignment of 'lowaddr' as zero.
There is already a piece of codes inside the segment traversal loop
that checks for zero-sized loadable segments for not creating empty
ROM blobs. Let's move this check to the beginning of the loop to
cover both scenarios.

Even though the BLAST command isn't fully implemented in QEMU, the DMA_STAT_BCMBLT
bit should be set after the command has been issued to indicate that the command
has completed.
This fixes an issue with the DC390 DOS driver which issues the BLAST command as
part of its normal error recovery routine at startup, and otherwise sits in a
tight loop waiting for DMA_STAT_BCMBLT to be set before continuing.

The setting of DMA_STAT_DONE at the end of a DMA transfer can be configured to
generate an interrupt, however the Linux driver manually checks for DMA_STAT_DONE
being set and if it is, considers that a DMA transfer has completed.
If DMA_STAT_DONE is set but the ESP device isn't indicating an interrupt then
the Linux driver considers this to be a spurious interrupt. However this can
occur in QEMU as there is a delay between the end of DMA transfer where
DMA_STAT_DONE is set, and the ESP device raising its completion interrupt.
This appears to be an incorrect assumption in the Linux driver as the ESP and
PCI DMA interrupt sources are separate (and may not be raised exactly
together), however we can work around this by synchronising the setting of
DMA_STAT_DONE at the end of a DMA transfer with the ESP completion interrupt.
In conjunction with the previous commit Linux is now able to correctly boot
from an am53c974 PCI SCSI device on the hppa C3700 machine without emitting
"iget: checksum invalid" and "Spurious irq, sreg=10" errors.

The am53c974/dc390 PCI interrupt has two separate sources: the first is from the
internal ESP device, and the second is from the PCI DMA transfer logic.
Update the ESP interrupt handler so that it sets DMA_STAT_SCSIINT rather than
driving the PCI IRQ directly, and introduce a new esp_pci_update_irq() function
to generate the correct PCI IRQ level. In particular this fixes spurious interrupts
being generated by setting DMA_STAT_DONE at the end of a transfer if DMA_CMD_INTE_D
isn't set in the DMA_CMD register.

The current code in esp_pci_dma_memory_rw() sets the DMA address to the value
of the DMA_SPA (Starting Physical Address) register which is incorrect: this
means that for each callback from the SCSI layer the DMA address is set back
to the starting address.
In the case where only a single SCSI callback occurs (currently for transfer
lengths < 128kB) this works fine, however for larger transfers the DMA address
wraps back to the initial starting address, corrupting the buffer holding the
data transferred to the guest.
Fix esp_pci_dma_memory_rw() to use the DMA_WAC (Working Address Counter) for
the DMA address which is correctly incremented across multiple SCSI layer
transfers.

This is a follow-up on commit 89965db43c "hw/isa/piix3: Avoid Xen-specific
variant of piix3_write_config()" which introduced
piix_intx_routing_notifier_xen(). This function is implemented in board code but
accesses the PCI configuration space of the PIIX ISA function to determine the
PCI interrupt routes. Avoid this by reusing pci_device_route_intx_to_irq() which
makes piix_intx_routing_notifier_xen() more device-agnostic.
One remaining improvement would be making piix_intx_routing_notifier_xen()
agnostic towards the number of PCI interrupt routes and move it to xen-hvm.
This might be useful for possible Q35 Xen efforts but remains a future exercise
for now.

'can_do_io' is specific to TCG. It was added to other
accelerators in 626cf8f4c6 ("icount: set can_do_io outside
TB execution"), then likely copy/pasted in commit c97d6d2cdf
("i386: hvf: add code base from Google's QEMU repository").
Having it set in non-TCG code is confusing, so remove it from
QTest / HVF / KVM.
