-# Interface variables:
-#
-# QB_XEN_U_BOOT_SCR :
-# If this variable is set, this class will generate the u-boot script image file
-# It must be set to the name of the compiled command file that u-boot will tftp
-# from the image deploy directory during boot, currently: "boot.scr.uimg"
-#
-# QB_XEN_CMDLINE_EXTRA :
-# A string to be appended to the default Xen hypervisor boot command line,
-# for supplying Xen boot options.
-# The device tree that this bbclass generates will contain Xen command
-# line options to connect the Xen console to the Qemu serial port.
-#
-# QB_XEN_LOAD_ADDR :
-# The hypervisor load address
-#
-# QB_XEN_DOM0_BOOTARGS :
-# A string for specifying Dom0 boot options for the Xen section of the device
-# tree.
-#
-# QB_XEN_UBOOT_SCR_TASK_DEPENDS:
-# The task dependencies for the u-boot script generation. A default is provided.
-#
-# QB_XEN_DOMAIN_MODULES:
-# A space-separated list of colon-separated entries:
-# "<file for the module>:<load memory address>:<module compatibility string>"
-
-# Set the default value for this variable to empty: no file generated.
