[PULL 16/27] i386: correctly select code in hw/i386 that depends on other components

Posted by Paolo Bonzini 6 months, 2 weeks ago

fw_cfg.c and vapic.c are currently included unconditionally but
depend on other components.  vapic.c depends on the local APIC,
while fw_cfg.c includes a piece of AML builder code that depends
on CONFIG_ACPI.
