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.

This class can be inherited by u-boot recipes to create extlinux.conf
and boot using menu options.

U-boot with extlinux support is machine dependent, so to use this class
you need to set UBOOT_EXTLINUX to 1 in machine configuration file and
also set root= kernel cmdline UBOOT_EXTLINUX_ROOT. This variable is used
to pass root kernel cmdline, e.g:

UBOOT_EXTLINUX_ROOT = "root=/dev/mmcblk2p2"
