The U-Boot environment resides on a UBI volume. The uuu script
relies on the environment to save part of the commands that
U-Boot needs to execute after reboot in the middle of the
installation. If the UBI volume 'uboot_config' does not exist
the installer fails.
This commit:
- Creates a function -on the uuu script only- for obtaining
the result of running any U-Boot command (0=success, 1=error).
- Checks the existance of 'uboot_config' volume.
- Runs 'ubivolscript' script to create the UBI volumes layout
that generates the environment volume if it doesn't exist.
- Increases the timeout for running the 'ubivolscript' since
there are occasions in which 'ubi part' (which is part of the
script) takes more time (if it cannot find the fastmap).
