Introduce bread new loongarch64-efi board, with skeleton
from aarch64-efi board.

It corverd most LoongArch64 systems.

Linux 6.6, as the most recent LTS kernel, was chosen
to ensure proper architecture support is included.

A developer entry is created for myself for future contacts
as well.

+The loongarch64_efi_defconfig allows to build a minimal Linux system that
+can boot on all loongarch64 systems providing an EFI firmware.
+
+This includes almost all Loongson-3 series workstations and servers.
+
+Building and booting
+====================
+
+$ make loongarch64_efi_defconfig
+$ make
+
+The file output/images/disk.img is a complete disk image that can be
+booted, it includes the grub2 bootloader, Linux kernel and root
+filesystem.
+
+Testing under Qemu
+==================
+
+This image can also be tested using Qemu:
+
+qemu-system-loongarch64 \
+	-M virt \
+	-cpu la464 \
+	-nographic \
+	-bios </path/to/QEMU_EFI.fd> \
+	-drive file=output/images/disk.img,if=none,format=raw,id=hd0 \
+	-device virtio-blk-pci,drive=hd0 \
+	-netdev user,id=eth0 \
+	-device virtio-net-pci,netdev=eth0
+
+Note that </path/to/QEMU_EFI.fd> needs to point to a valid loongarch64 UEFI
+firmware image for qemu.
+It may be provided by your distribution as a edk2-loongarch64 package,
+in path such as /usr/share/edk2/loongarch64/QEMU_EFI.fd .
