[Qemu-devel] [PATCH v3 07/28] riscv: sifive_u: Set the minimum number of cpus to 2

[Bin Meng <bmeng.cn@gmail.com>]

It is not useful if we only have one management CPU.

Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

---

Changes in v3:
- use management cpu count + 1 for the min_cpus

Changes in v2:
- update the file header to indicate at least 2 harts are created
