+Compiled-in block device support
+CONFIG_BLK_DEV_CIBD
+  Set this to have the contents of drivers/block/cibd.h copied into
+  the ramdisk. The cibd.h file is generated using the makeh script and
+  the file2hex program in the drivers/block/ directory. This is useful
+  if you don't have any real device to boot from.

 Loopback device support
 CONFIG_BLK_DEV_LOOP
   Saying Y here will allow you to use a regular file as a block
