Hi,
This patch implements CANFD controller for xlnx-versal-virt machine. There are
two controllers CANFD0@0xFF06_ and CANFD1@0xFF07_ are connected to the
machine.
Also, added basic qtests for data exchange between both the controllers in
various supported configs.
Changelog:
v1->v2

This patch series contains 2 performance optimizations that

In the first optimization, the check for empty breakpoints' queue

Weird coincidence, that is a bug that's been in the tree for months
We used to rely on QEMU_CFLAGS to expose the debug flags but now this
is synthesised by meson and only available to the main build. Add our
own flags if we detect the build has been enabled with
CONFIG_DEBUG_TCG (which is the default for --enable-debug anyway).

Now that cs->interrupt_request indicates if there is any unmasked
interrupt, checking if the CPU has work to do can be simplified to a
single check that works for all CPU models.

How about set_mempolicy():

Currently we're writing the NULL section header if we overflow the
physical header number in the ELF header. But in the future we'll add
custom section headers AND section data.
To facilitate this we need to rearange section handling a bit. As with
the other ELF headers we

Add hooks which architectures can use to add arbitrary data to custom
sections.
Also add a section name string table in order to identify section
