There are elements sw_ipmap and sw_coremap, which is usd to speed
up irq injection flow. They are saved and restored in vmstate during
migration, indeed they can calculated from hw registers. Here
post_load is added for get sw_ipmap and sw_coremap from extioi hw
state.

per-board rather percpu,
for iocsr registers specified for cpu, MemTxAttrs.requester_id
can be parsed for the cpu. With this patches, the total address space
on board will be simple, only iocsr address space and system memory,
rather than the number of cpu and system memory.

On LoongArch system, there is iocsr address space simliar system io
address space on x86. And each cpu has its separate iocsr address space now,
with this patch, iocsr address space is changed with per-board, and
MemTxAttrs.requester_id is used to differentiate cpu cores.

Timer emulation sometimes is problematic especially when vm is running in
kvm mode. This patch adds registers dump support relative with timer
hardware, so that it is easier to find the problems.

value like 0x1e20/7.
Another way multiple virtio-mmio devices should be added like other arches.
And there should be fdt/acpi table added for the device so that users can use
it.

Good catch.
In theory, it is logical id, and it can be not equal to physical id.
However it must be equal to _UID in cpu dsdt table which is missing
now.
Can pptt table parse error be fixed if cpu dsdt table is added?
