The number of memory banks in QEMU is not bounded by 1.
In this example we have two banks:
qemu-system-riscv64 \
-machine virt \
-nographic \
-m 8192 \
-smp 8,sockets=2,cores=4,threads=1 \
-numa node,cpus=0-3,mem=4096 \
-numa node,cpus=4-7,mem=4096 \
-kernel u-boot
As we will see RISC-V NUMA systems using U-Boot
we should be able to emulate these.
Use the default value defined in /Kconfig as 4.

The number of memory banks in QEMU is not bounded by 1.
In this example we have two banks:
qemu-system-aarch64 \
-machine virt \
-nographic \
-cpu cortex-a72 \
-m 8G \
-smp 8,sockets=2,cores=4,threads=1 \
-object memory-backend-ram,id=mem0,size=4G \
-numa node,cpus=0-3,memdev=mem0 \
-object memory-backend-ram,id=mem1,size=4G \
-numa node,cpus=4-7,memdev=mem1 \
-bios u-boot.bin
Use the default value defined in /Kconfig as 4.
