OvmfPkg/LoongArchVirt: Add SATA support 
SATA CD-ROMS are still conventionally used in many
virtual environments, so it's nice to support them
out of the box.

Tested with QEMU 9.2.3 with the following controller
and drive:

  qemu-system-loongarch64 -M virt [...]  \
    -device ahci,id=ahci0,multifunction=on,bus=pcie.0,addr=0x7 \
    -drive if=none,id=drive-sata2,media=cdrom,format=raw,aio=threads,file=/path/to/bootable.iso \
    -device ide-cd,bus=ahci0.2,drive=drive-sata2,id=sata2,bootindex=102

LoongArch QEMU virt platform

Overview

LoongArch QEMU virt is a generic platform that does not require any actual hardware. The minimum required QEMU version is 8.1, the minimum required GCC version is GCC13, the minimum required Binutils version is 2.40.

Prepare (X86 Linux Environment)

Fedora39 and higher

Install LoongArch64 cross compiler, LoongArch system QEMU.

yum install gcc-loongarch64-linux-gnu
yum install qemu-system-loongarch64

Others X86 OS ENV

Configure cross-tools

Download:

wget https://github.com/loongson/build-tools/releases/download/2023.08.08/x86_64-cross-tools-loongarch64-binutils_2.41-gcc_13.2.0.tar.xz

Configure the cross-tools environment:

mkdir /opt/loongarch64_cross-toolchain/
tar -vxf x86_64-cross-tools-loongarch64-binutils_2.41-gcc_13.2.0.tar.xz -C /opt/loongarch64_cross-toolchain/
export PATH=/opt/loongarch64_cross-toolchain/cross-tools/bin:$PATH

Note: Please obtain the latest cross-compilation toolchains.
