Change 32558ce7a4 introduced specific directories for the socket dir
when using python/qemu/machine.py:QEMUMachine. iotests probably
didn't catch the condition that two simultaneous QEMUMachine
instances, without manually set temporary or socket dirs would clash.
Having two QEMUMachine instances is a condition expected for many
acceptance tests, and it's already used by the migration tests.

This patch set contains a handful of small fixes for RISC-V targets that
I'd like to target for the 4.2 soft freeze. They include:
* A fix to allow the debugger to access the state of all privilege
modes, as opposed to just the currently executing one.
* A pair of cleanups to implement cpu_do_transaction_failed.
* Fixes to the device tree.
* The addition of various memory regions to make the sifive_u machine
more closely match the HiFive Unleashed board.
* Fixes to our GDB interface to allow CSRs to be accessed.
* A fix to a memory leak pointed out by coverity.
* A fix that prevents PMP checks from firing incorrectly.
This passes "make chcek" and boots Open Embedded for me.

If you want to test the machine, it doesn't yet boot a MacROM, but you can
boot a linux kernel from the command line.
You can install your own disk using debian-installer with:
./qemu-system-m68k \
-M q800 \
-serial none -serial mon:stdio \
-m 1000M -drive file=m68k.qcow2,format=qcow2 \
-net nic,model=dp83932,addr=09:00:07:12:34:57 \
-append "console=ttyS0 vga=off" \
-kernel vmlinux-4.15.0-2-m68k \
-initrd initrd.gz \
-drive file=debian-9.0-m68k-NETINST-1.iso \
-drive file=m68k.qcow2,format=qcow2 \
-nographic
If you use a graphic adapter instead of "-nographic", you can use "-g"
to set the size of the display (I use "-g 1600x800x24").

There is no DMA in Quadra 800, so the CPU reads/writes the data from the
PDMA register (offset 0x100, ESP_PDMA in hw/m68k/q800.c) and copies them
to/from the memory.
There is a nice assembly loop in the kernel to do that, see
linux/drivers/scsi/mac_esp.c:MAC_ESP_PDMA_LOOP().
The start of the transfer is triggered by the DREQ interrupt (see linux
mac_esp_send_pdma_cmd()), the CPU polls on the IRQ flag to start the
transfer after a SCSI command has been sent (in Quadra 800 it goes
through the VIA2, the via2-irq line and the vIFR register)
The Macintosh hardware includes hardware handshaking to prevent the CPU
from reading invalid data or writing data faster than the peripheral
device can accept it.
This is the "blind mode", and from the doc:
"Approximate maximum SCSI transfer rates within a blocks are 1.4 MB per
second for blind transfers in the Macintosh II"

To prepare following patches move do_cmd and DMA special case
from handle_ti() to esp_do_dma().
This part of the code must be only executed with real DMA, not with
pseudo-DMA. And PDMA is detected in esp_do_dma(), so move this part
of the code in esp_do_dma(). We keep the code in handle_ti_cmd()
in the case no DMA is done.

riscv_cpu_tlb_fill() uses the `size` parameter to check PMP violation
using pmp_hart_has_privs().
However, if the size is unknown (=0), the ending address will be
`addr - 1` as it is `addr + size - 1` in `pmp_hart_has_privs()`.
This always causes a false PMP violation on the starting address of the
range, as `addr - 1` is not in the range.
In order to fix, we just assume that all bytes from addr to the end of
the page will be accessed if the size is unknown.

Coverity (CID 1405786) thinks that there is a possible memory leak as
we don't guarantee that the memory allocated from riscv_find_firmware()
is freed. This is a false positive, but let's tidy up the code to fix
the warning.

Nettle 3.5.0 will add support for the XTS mode. Use this because long
term we wish to delete QEMU's XTS impl to avoid carrying private crypto
algorithm impls.
Unfortunately this degrades nettle performance from 612 MB/s to 568 MB/s
as nettle's XTS impl isn't so well optimized yet.

Libgcrypt 1.8.0 added support for the XTS mode. Use this because long
term we wish to delete QEMU's XTS impl to avoid carrying private crypto
algorithm impls.
As an added benefit, using this improves performance from 531 MB/sec to
670 MB/sec, since we are avoiding several layers of function call
indirection.
This is even more noticable with the gcrypt builds in Fedora or RHEL-8
which have a non-upstream patch for FIPS mode which does mutex locking.
This is catastrophic for encryption performance with small block sizes,
meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

This is a simple plugin to track which translation blocks are call
most often. As we don't have a view of the internals of TCG we can
only work by the address of the start of the block so we also need to
tracks how often the address is translated.
As there will be multiple blocks starting at the same address. We can
try and work around this by futzing the value to feed to the hash with
the insn count.

If CONFIG_PLUGINS is enabled then lets enable testing for all our TCG
targets. This is a simple smoke test that ensure we don't crash or
otherwise barf out by running each plugin against each test.
There is a minor knock on effect for additional runners which need
specialised QEMU_OPTS which will also need to declare a plugin version
of the runner. If this gets onerous we might need to add another
helper.
Checking the results of the plugins is left for a later exercise.
