Subject: hw/loongarch/boot: Use warn_report when no kernel filename
X-Git-Tag: v9.2.0-rc0~25^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6495c577bd7edf53bd89e9f26c1f6263fcf7e71a;p=thirdparty%2Fqemu.git

hw/loongarch/boot: Use warn_report when no kernel filename

When we run “qemu-system-loongarch64 -qmp stdio -vnc none -S”,
we get an error message “Need kernel filename” and then we can't use qmp cmd to query some information.
So, we just throw a warning and then the cpus starts running from address VIRT_FLASH0_BASE.
