This series patch add softmmu support for LoongArch.
The latest kernel:
* https://github.com/loongson/linux/tree/loongarch-next
The latest uefi:
* https://github.com/loongson/edk2
* https://github.com/loongson/edk2-platforms
The manual:
* https://github.com/loongson/LoongArch-Documentation/releases/tag/2021.10.11
You can get LoongArch qemu series like this:
git clone https://github.com/loongson/qemu.git
git checkout tcg-dev
Changes for v5:
1. Fix host bridge map irq function.
2. Move cpu timer init function into machine init.
3. Adjust memory region layout.
4. Add the documentation at docs/system/loongarch/loongson3.rst.
- Introduction to 3a5000 virt.
- Output of "info mtree".
Changes for v4:
1. Uefi code is open and add some fdt interface to pass info between qemu and
uefi.
2. Use a per cpu address space for iocsr.
3. Modify the tlb emulation.
4. Machine and board code mainly follow Mark's advice.
5. Adjust pci host space map.
6. Use more memregion to simplify the interrupt controller's emulate.
Changes for v3:
1.Target code mainly follow Richard's code review comments.
2.Put the csr and iocsr read/write instruction emulate into 2 different patch.
3.Simply the tlb emulation.
4.Delete some unused csr registers defintion.
5.Machine and board code mainly follow Mark's advice, discard the obsolete
interface.
6.NUMA function is removed for it is not completed.
7.Adjust some format problem and the Naming problem

2.Adjust the order of the patch.
3.Put all the binaries on the github.
4.Modify some emulate errors when use the kernel from the github.
5.Adjust some format problem and the Naming problem
6.Others mainly follow Richard's code review comments.
Please help review!
Thanks
