From: Quirin Gylstorff <quirin.gylstorff@...>

The dependency to ${U_BOOT} is unnecessary for the
SWUPDATE build and the package deployment. The package
`u-boot-${MACHINE}-config` is requested for fw_env.config
from a custom u-boot build. SWUpdate uses fw_env.config
to read/write the u-boot environment.

If the Package `u-boot-${MACHINE}-config` is not activated during
the build, by setting `U_BOOT_CONFIG_PACKAGE` to '1',
then do not add `u-boot-${MACHINE}-config` to the
swupdate dependencies.

U-Boot build by Debian provides example configurations
for different boards with the package u-boot-tools.

If u-boot-tools are installed these examples can be found
at config /usr/share/doc/u-boot-tools/examples/.
