8d96788cb1 hw/loongarch: Refine system dram memory region
For system dram memory region, it is not necessary to use numa node
information. There is only low memory region and high memory region.

Remove numa node information for ddr memory region here, it can reduce
memory region number on LoongArch virt machine.

3cc451cbce hw/loongarch: Refine fwcfg memory map
Memory map table for fwcfg is used for UEFI BIOS, UEFI BIOS uses the first
entry from fwcfg memory map as the first memory HOB, the second memory HOB
will be used if the first memory HOB is used up.

Memory map table for fwcfg does not care about numa node, however in
generic the first memory HOB is part of numa node0, so that runtime
memory of UEFI which is allocated from the first memory HOB is located
at numa node0.

09ec65794f hw/loongarch: Refine fadt memory table for numa memory
One LoongArch virt machine platform, there is limitation for memory
map information. The minimum memory size is 256M and minimum memory
size for numa node0 is 256M also. With qemu numa qtest, it is possible
that memory size of numa node0 is 128M.

Limitations for minimum memory size for both total memory and numa
node0 is removed for fadt numa memory table creation.

d641ec30be kconfig: express dependency of individual boards on libfdt
Now that boards are enabled by default and the "CONFIG_FOO=y"
entries are gone from configs/devices/, there cannot be any more
a conflicts between the default contents of configs/devices/
and a failed "depends on" clause.

With this change, each individual board or target can express
whether it needs FDT.  It can then include the common code in the
build via "select DEVICE_TREE", which will also as tell meson to link
with libfdt.

This allows building non-microvm x86 emulators without having
libfdt available.

f532cf0131 hw/loongarch: Refine default numa id calculation
With numa_test test case, there is subcase named test_def_cpu_split(),
there are 8 sockets and 2 numa nodes. Here is command line:
"-machine smp.cpus=8,smp.sockets=8 -numa node,memdev=ram -numa node"

The required result is:
  node 0 cpus: 0 2 4 6
  node 1 cpus: 1 3 5 7
Test case numa_test fails on LoongArch, since the actual result is:
  node 0 cpus: 0 1 2 3
  node 1 cpus: 4 5 6 7

It will be better if all the cpus in one socket share the same numa
node. Here socket id is used to calculate numa id in function
virt_get_default_cpu_node_id().

c6e9847fc4 loongarch: Change the UEFI loading mode to loongarch
The UEFI loading mode in loongarch is very different
from that in other architectures:loongarch's UEFI code
is in rom, while other architectures' UEFI code is in flash.

loongarch UEFI can be loaded as follows:
-machine virt,pflash=pflash0-format
-bios ./QEMU_EFI.fd

Other architectures load UEFI using the following methods:
-machine virt,pflash0=pflash0-format,pflash1=pflash1-format

loongarch's UEFI loading method makes qemu and libvirt incompatible
when using NVRAM, and the cost of loongarch's current loading method
far outweighs the benefits, so we decided to use the same UEFI loading
scheme as other architectures.

10a8f7d25a hw/intc/loongarch_extioi: Add dynamic cpu number support
On LoongArch physical machine, one extioi interrupt controller only
supports 4 cpus. With processor more than 4 cpus, there are multiple
extioi interrupt controllers; if interrupts need to be routed to
other cpus, they are forwarded from extioi node0 to other extioi nodes.

On virt machine model, there is simple extioi interrupt device model.
All cpus can access register of extioi interrupt controller, however
interrupt can only be route to 4 vcpu for compatible with old kernel.

This patch adds dynamic cpu number support about extioi interrupt.
With old kernel legacy extioi model is used, however kernel can detect
and choose new route method in future, so that interrupt can be routed to
all vcpus.

5e90b8db38 hw/loongarch/virt: Set iocsr address space per-board rather than percpu
LoongArch system has iocsr address space, most iocsr registers are
per-board, however some iocsr register spaces banked for percpu such
as ipi mailbox and extioi interrupt status. For banked iocsr space,
each cpu has the same iocsr space, but separate data.

This patch changes iocsr address space 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.

hw/loongarch: Fix ACPI processor id off-by-one error
In hw/acpi/aml-build.c:build_pptt() function, the code assumes that the
ACPI processor id equals to the cpu index, for example if we have 8
cpus, then the ACPI processor id should be in range 0-7.

However, in hw/loongarch/acpi-build.c:build_madt() function we broke the
assumption. If we have 8 cpus again, the ACPI processor id in MADT table
would be in range 1-8. It violates the following description taken from
ACPI spec 6.4 table 5.138:

If the processor structure represents an actual processor, this field
must match the value of ACPI processor ID field in the processor’s entry
in the MADT.

It will break the latest Linux 6.5-rc6 with the
following error message:

ACPI PPTT: PPTT table found, but unable to locate core 7 (8)
Invalid BIOS PPTT

Here 7 is the last cpu index, 8 is the ACPI processor id learned from
MADT.

With this patch, Linux can properly detect SMT threads when "-smp
8,sockets=1,cores=4,threads=2" is passed:

Thread(s) per core:  2
Core(s) per socket:  2
Socket(s):           2

The detection of number of sockets is still wrong, but that is out of
scope of the commit.
