This  series was part of the previous PR to add generic error injection
support on GHES. It depends on a cleanup patch series sent yesterday:

https://lore.kernel.org/qemu-devel/c3e608a16a795b2d2be476eddc3707febcdb1ca3.1731406254.git.mchehab+huawei@kernel.org/T/#m60839c88a009f04bc73f75832ccb6a41523259ef

It contains the changes of the math used to calculate offsets at HEST table 
and hardware_error firmware file. It prepares for the addition of GHES
error injection.

The first patch was previously at the cleanup series. It prepares
the logic to support multiple sources.

The second patch adds a new firmware file to store HEST address.

The third patch use the new firmware to calculate offsets using
HEST table.

Patches 4 and 5 add migration support. They assume that this
series will be merged for qemu 9.2 (maybe it is too late for that,
as QEMU is now on soft freeze). 

I tested migration using both virt-9.1 and virt-9.2 machines
on qemu 9.2.

I also tested migration with:

	qemu-9.1 -M virt-9.1 -cpu cortex-a57 => qemu-9.2 -M virt-9.1 -cpu cortex-a57
	qemu-9.2 -M virt-9.1 -cpu cortex-a57 => qemu-9.1 -M virt-9.1 -cpu cortex-a57

Mauro Carvalho Chehab (6):
  acpi/ghes: Prepare to support multiple sources on ghes
  acpi/ghes: add a firmware file with HEST address
  acpi/ghes: rename the function which gets hw error offsets
  acpi/ghes: Use HEST table offsets when preparing GHES records
  acpi/generic_event_device: Update GHES migration to cover hest addr
  acpi/generic_event_device: add logic to detect if HEST addr is
    available
