+# uboot-extlinux-config.bbclass
+#
+# This class allow the extlinux.conf generation for U-Boot use. The
+# U-Boot support for it is given to allow the Generic Distribution
+# Configuration specification use by OpenEmbedded-based products.
+#
+# External variables:
+#
+# UBOOT_EXTLINUX_CONSOLE - Set to "console=ttyX" to change kernel boot
+# default console.
+# UBOOT_EXTLINUX_LABELS - A list of targets for the automatic config.
+# UBOOT_EXTLINUX_KERNEL_ARGS - Add additional kernel arguments.
+# UBOOT_EXTLINUX_KERNEL_IMAGE - Kernel image name.
+# UBOOT_EXTLINUX_FDTDIR - Device tree directory.
+# UBOOT_EXTLINUX_FDT - Device tree file.
+# UBOOT_EXTLINUX_INITRD - Indicates a list of filesystem images to
+# concatenate and use as an initrd (optional).
+# UBOOT_EXTLINUX_MENU_DESCRIPTION - Name to use as description.
+# UBOOT_EXTLINUX_ROOT - Root kernel cmdline.
+# UBOOT_EXTLINUX_TIMEOUT - Timeout before DEFAULT selection is made.
+# Measured in 1/10 of a second.
+# UBOOT_EXTLINUX_DEFAULT_LABEL - Target to be selected by default after
+# the timeout period
+#
+# If there's only one label system will boot automatically and menu won't be
+# created. If you want to use more than one labels, e.g linux and alternate,
+# use overrides to set menu description, console and others variables.
+#
+# Ex:
+#
+# UBOOT_EXTLINUX_LABELS ??= "default fallback"
+#
+# UBOOT_EXTLINUX_DEFAULT_LABEL ??= "Linux Default"
+# UBOOT_EXTLINUX_TIMEOUT ??= "30"
+#
+# UBOOT_EXTLINUX_KERNEL_IMAGE_default ??= "../zImage"
+# UBOOT_EXTLINUX_MENU_DESCRIPTION_default ??= "Linux Default"
+#
+# UBOOT_EXTLINUX_KERNEL_IMAGE_fallback ??= "../zImage-fallback"
+# UBOOT_EXTLINUX_MENU_DESCRIPTION_fallback ??= "Linux Fallback"
+#
+# Results:
+#
+# menu title Select the boot mode
+# TIMEOUT 30
+# DEFAULT Linux Default
+# LABEL Linux Default
+# KERNEL ../zImage
+# FDTDIR ../
+# APPEND root=/dev/mmcblk2p2 rootwait rw console=${console}
+# LABEL Linux Fallback
+# KERNEL ../zImage-fallback
+# FDTDIR ../
+# APPEND root=/dev/mmcblk2p2 rootwait rw console=${console}
