If you try to run a 16 or 32 threaded test, you're going to run out of
memory very quickly with qom-test and a few others. Bump the memory
limit to try to scale with larger-core machines.
Granted, this means that a 16 core processor is going to ask for 16GB,
but you *probably* meet that requirement if you have such a machine.
512MB per core didn't seem to be enough to avoid ENOMEM and SIGABRTs in
the test cases in practice on a six core machine; so I bumped it up to
1GB which seemed to help.
Add this magic in early to the configuration process so that the
config file, if provided, can still override it.

Ubuntu 18.04 is out of our support window, and Ubuntu 20.04 does not
support i386 anymore. The debian project does, but they do not provide
any cloud images for it, a new expect-style script would have to be
written.
Since we have i386 cross-compiler tests hosted on GitLab CI, we don't
need to support this VM test anymore.

18.04 has fallen out of our support window, so move ubuntu.aarch64
forward to ubuntu 20.04, which is now our oldest supported Ubuntu
release.
Notes:
This checksum changes periodically; use a fixed point image with a known
checksum so that the image isn't re-downloaded on every single
invocation. (The checksum for the 18.04 image was already incorrect at
the time of writing.)
Just like the centos.aarch64 test, this test currently seems very
flaky when run as a TCG test.

Switch this test over to using a cloud image like the base CentOS8 VM
test, which helps make this script a bit simpler too.
Note: At time of writing, this test seems pretty flaky when run without
KVM support for aarch64. Certain unit tests like migration-test,
virtio-net-failover, test-hmp and qom-test seem quite prone to fail
under TCG. Still, this is an improvement in that at least pure build
tests are functional.

There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.
All Raspberry Pi models 1-3 (based on bcm2835) have
Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25):
/* dma channel 11-14 share one irq */
This information is repeated in the driver code
(drivers/dma/bcm2835-dma.c +1344):
/*
* in case of channel >= 11
* use the 11th interrupt and that is shared
*/
In this patch channels 0--10 and 11--14 are handled separately.

The architecture requires that for faults on loads and stores which
do writeback, the syndrome information does not have the ISS
instruction syndrome information (i.e. ISV is 0). We got this wrong
for the load and store instructions covered by disas_ldst_reg_imm9().
Calculate iss_valid correctly so that if the insn is a writeback one
it is false.

Our sensor test requires both reading and writing from a sensor's
QOM property. So we need to make the input of ADC module R/W instead
of write only for that to work.

The correct bit for the CONV bit in NPCM7XX ADC is bit 13. This patch
fixes that in the module, and also lower the IRQ when the guest
is done handling an interrupt event from the ADC module.

In regime_tcr() we return the appropriate TCR register for the
translation regime. For Secure EL2, we return the VSTCR_EL2 value,
but in this translation regime some fields that control behaviour are
in VTCR_EL2. When this code was originally written (as the comment
notes), QEMU didn't care about any of those fields, but we have since
added support for features such as LPA2 which do need the values from
those fields.
Synthesize a TCR value by merging in the relevant VTCR_EL2 fields to
the VSTCR_EL2 value.

Change the representation of the TCR_EL* registers in the CPU state
struct from struct TCR to uint64_t. This allows us to drop the
custom vmsa_ttbcr_raw_write() function, moving the "enforce RES0"
checks to their more usual location in the writefn
vmsa_ttbcr_write(). We also don't need the resetfn any more.

We have a bug in our handling of accesses to the AArch32 VTCR
register on big-endian hosts: we were not adjusting the part of the
uint64_t field within TCR that the generated code would access. That
can be done with offsetoflow32(), by using an ARM_CP_STATE_BOTH cpreg
struct, or by defining a full set of read/write/reset functions --
the various other TCR cpreg structs used one or another of those
strategies, but for VTCR we did not, so on a big-endian host VTCR
accesses would touch the wrong half of the register.
Use offsetoflow32() in the VTCR register struct. This works even
though the field in the CPU struct is currently a struct TCR, because
the first field in that struct is the uint64_t raw_tcr.
None of the other TCR registers have this bug -- either they are
AArch64 only, or else they define resetfn, writefn, etc, and
expect to be passed the full struct pointer.
