[Qemu-devel] [PATCH v5 5/5] pc_sysfw: change rom_only default to 0

[Jordan Justen <jordan.l.justen@intel.com>]

Now KVM can support a flash memory. This feature depends on
KVM_CAP_READONLY_MEM, which was introduced in Linux 3.7.

Flash memory will only be enabled if a pflash device is
created. (For example, by using the -pflash command line
parameter.)
