We can now easily see the machines automatically creating SDcard:

$ git grep 'auto_create_sdcard = true'
hw/arm/cubieboard.c:125:    mc->auto_create_sdcard = true;
hw/arm/integratorcp.c:691:    mc->auto_create_sdcard = true;

hw/arm/npcm7xx_boards.c:510:    mc->auto_create_sdcard = true;
hw/arm/npcm7xx_boards.c:523:    mc->auto_create_sdcard = true;
hw/arm/npcm7xx_boards.c:536:    mc->auto_create_sdcard = true;
hw/arm/omap_sx1.c:219:    mc->auto_create_sdcard = true;
hw/arm/omap_sx1.c:238:    mc->auto_create_sdcard = true;
hw/arm/orangepi.c:124:    mc->auto_create_sdcard = true;

hw/arm/realview.c:478:    mc->auto_create_sdcard = true;
