u-boot: Optionally deploy an environment or script file
Some boards are configured to read a script or environment file as part
of the u-boot boot sequence. This file, typically called 'uEnv.txt' or
'boot.scr', would be deployed alongside the u-boot binary. If a recipe
uses this u-boot.inc, such a file can be deployed by setting the optional
UBOOT_ENV parameter and including the file in the SRC_URI. For example:
SRC_URI_append_overo = "file://uEnv.txt"
UBOOT_ENV_overo = "uEnv"
