Grub does flash up some errors at the beginning but I'm having trouble making sense of any of them:

Using modules provided by bootloader in FDT
I only have the one disk in the system.
I guess I need to tweak xen to emit more information about what was failing. Should I just work of the master branch? Are Julien's patches to date going to get merged?

My patches are not yet merged. I need to respin them. Although it is unlikely to happen until mid next-week as I am away from tomorrow.

What version of GRUB are you using?
2.04-11 - so The current Debian Testing package with your patch applied. I'd avoided build grub from scratch to avoid screwing up the system but if it's just a drop in .efi binary then I can build from the vanilla tree.
[...]
I guess I need to tweak xen to emit more information about what was failing. Should I just work of the master branch? Are Julien's patches to date going to get merged?
My patches are not yet merged. I need to respin them. Although it is unlikely to happen until mid next-week as I am away from tomorrow.

I tried to repro the issue but I cannot see any problems with the EFI+Grub+DeviceTree setup that I have here.
My suggestion would be to rebuild Grub and play around with the finalize_params_xen_boot function Julien patched. I would try increasing additional_size to 0x2000 to see if it helps.
I would also add a printk to dt_device_is_compatible: it would be very verbose, but it would tell you exactly which one is the offending string. However, if it is a DTB size miscalculation by Grub, that is not going to help much.

That's understandable. Before switching to GRUB upstream, I would like to understand which compatible is likely not NUL-terminated.
Would you mind to apply this patch in Xen and post the full log?

This patch will printk the compatible for each call to dt_device_is_compatible() and print a message if one property is not NUL-terminated.

What version of GRUB are you using?
2.04-11 - so The current Debian Testing package with your patch applied. I'd avoided build grub from scratch to avoid screwing up the system but if it's just a drop in .efi binary then I can build from the vanilla tree.
That's understandable. Before switching to GRUB upstream, I would like to understand which compatible is likely not NUL-terminated.
Would you mind to apply this patch in Xen and post the full log?

Full log further bellow but it looks like it crashes while going through the a806 config space. Is this something that grub is likely to mess with or does it point to a problem with the EDK2 build? Does the build have the tables embedded in it or does it extract it from some ROM device on the board?

2.04-11 - so The current Debian Testing package with your patch applied. I'd avoided build grub from scratch to avoid screwing up the system but if it's just a drop in .efi binary then I can build from the vanilla tree.
That's understandable. Before switching to GRUB upstream, I would like to understand which compatible is likely not NUL-terminated.
Would you mind to apply this patch in Xen and post the full log?

Full log further bellow but it looks like it crashes while going through the a806 config space. Is this something that grub is likely to mess with or does it point to a problem with the EDK2 build? Does the build have the tables embedded in it or does it extract it from some ROM device on the board?

This is interesting: it doesn't look like the string is not NULL terminated. It looks like the FDT size wasn't reported correctly. Otherwise it would have at least printed "cplen XX" for the last node. (It might be worth re-running the same experiment passing sync_console on the Xen command line to be extra safe we aren't missing any console output.)
Basically, there is a dt_for_each_device_node loop which is iterating for each device node:
for ( dn = dt_host; dn != NULL; dn = dn->allnext )
For the node following /ap806/config-space@f0000000/system-controller@6f4000/pinctrl Xen crashes trying to access dn->full_name.
dn->full_name is set by unflatten_dt_node when unflattening the FDT.
I am guessing Grub is modifying the FDT incorrectly or doesn't update the FDT size correctly.

Well it looks like I can confirm that upstream grub fixes whatever the Debian stable and testing grubs have broken. However I still run into a problem once we get to the kernel:

I am guessing Grub is modifying the FDT incorrectly or doesn't update the FDT size correctly.
Well it looks like I can confirm that upstream grub fixes whatever the Debian stable and testing grubs have broken.

I know this one, let me explain.
It is difficult to implement ICPENDR/ISPENDR (and also ISACTIVER/ICACTIVER) in Xen. Currently we don't implement them at all. In the case of writing to ICPENDR, we return error causing the "Unhandled fault" strack trace you are seeing.
Looking at Linux mvebu_icu_irq_domain_alloc:
/* Make sure there is no interrupt left pending by the firmware */ err = irq_set_irqchip_state(virq, IRQCHIP_STATE_PENDING, false); if (err) goto free_msi;
In this case it would seem reasonably safe to ignore the ICPENDR request and continue. So, please try with the appended patch for Xen. We started ignoring writes to ICACTIVER for similar reasons. But a generic solution requires a proper implementation of these operations.

I suspect the ICPENDR problem is not an issue anymore. We are seeing another hang, maybe due to the lack of dom0_mem or something else.
The "Unhandled SMC/HVC" messages are interesting: Xen blocks SMC calls by default. The dom0 kernel here is trying to make two SiP calls, Xen blocks them and returns "unimplemented". I don't know if it causes any issues to the kernel but I can imagine that the kernel driver might refuse to continue. It is typically a firmware driver (drivers/firmware).
If the two calls are actually required to boot, then Xen should have a 'mediator' driver to filter the calls allowed from the ones that are not allowed. See for instance xen/arch/arm/platforms/xilinx-zynqmp-eemi.c. As a test, the appended patch allows all SMC calls for dom0:
