We're going to make the second UART not always a secure-only device.
Rename the constants VIRT_UART and VIRT_SECURE_UART to VIRT_UART0
and VIRT_UART1 accordingly.

If there is more than one UART in the DTB, then there is no guarantee
on which order a guest is supposed to initialise them. The standard
solution to this is "serialN" entries in the "/aliases" node of the
dtb which give the nodename of the UARTs.
At the moment we only have two UARTs in the DTB when one is for
the Secure world and one for the Non-Secure world, so this isn't
really a problem. However if we want to add a second NS UART we'll
need the aliases to ensure guests pick the right one.

This commit modifies the dwc2_hsotg_read() and dwc2_hsotg_write() functions
to handle invalid address access gracefully. Instead of using
g_assert_not_reached(), which causes the program to abort, the functions
now log an error message and return a default value for reads or do
nothing for writes.
This change prevents the program from aborting and provides clear log
messages indicating when an invalid memory address is accessed.

This commit updates the a9_gtimer_get_current_cpu() function to handle
cases where QTest is enabled. When QTest is used, it returns 0 instead
of dereferencing the current_cpu, which can be NULL. This prevents the

Since commit 83aa1baa06 we have been running the build for Coverity
Scan as a Gitlab CI job, rather than the old setup where it was run
on a local developer's machine. This is working well, but the
absolute paths of files are different for the Gitlab CI job, which
means that the regexes we use to identify Coverity components no
longer work. With Gitlab CI builds the file paths are of the form
/builds/qemu-project/qemu/accel/kvm/kvm-all.c
rather than the old
/qemu/accel/kvm/kvm-all.c
and our regexes all don't match.
Update all the regexes to start with .*/qemu/ . This will hopefully
avoid the need to change them again in future if the build path
changes again.
This change was made with a search-and-replace of (/qemu)?
to .*/qemu .

Julien reported that he has seen strange behaviour when running
Xen on QEMU using GICv2. When Xen migrates a guest's vCPU from
one pCPU to another while the vCPU is handling an interrupt, the
guest is unable to properly deactivate interrupts.
Looking at it a little closer, our GICv2 model treats
deactivation of SPI lines as if they were PPI's, i.e banked per
CPU core. The state for active interrupts should only be banked
for PPI lines, not for SPI lines.
Make deactivation of SPI lines unbanked, similar to how we
handle writes to GICD_ICACTIVER.
