Invert the 'no_sdcard' logic, renaming it as the more explicit "auto_create_sdcard". Machines are supposed to create a SD Card drive when this flag is set. In many cases it doesn't make much sense (as boards don't expose SD Card host controller), but this is patch only aims to expose that nonsense; so no logical change intended (mechanical patch using gsed). Most of the changes are: - mc->no_sdcard = ON_OFF_AUTO_OFF; + mc->auto_create_sdcard = true; Except in . hw/core/null-machine.c . hw/arm/xilinx_zynq.c . hw/s390x/s390-virtio-ccw.c where the disabled option is manually removed (since default): - mc->no_sdcard = ON_OFF_AUTO_ON; + mc->auto_create_sdcard = false; - mc->auto_create_sdcard = false; and in system/vl.c we change the 'default_sdcard' type to boolean.
