# Fixup for the libubootenv which rely on uboot-config class for no good reason.
#
# This is not intended to be permanent but we need to get the integration
# working and there is no good solution for now so we are adding this in a
# non-intrusive way and using the `IMX_DEFAULT_BOOTLOADER` as a guard to do any
# code execution.

       # FIXME: We need to provide the UBOOT_MACHINE or UBOOT_CONFIG to allow libubootenv to
       # build. This is caused by the commit below:

       # |
       # |     This mainly aims to involve in the sanity check of UBOOT_CONFIG and
       # |     UBOOT_MACHINE, it will throw a error message at recipe parsing time if
       # |     neither of them is set, and libubootenv would be skipped.
