A mechanism was introduced in U-Boot to dynamically locate the environment
copies within a NAND partition, skipping bad blocks and making full use of
the partition blocks.
To trigger this mechanism in Linux tools (fw_printenv/fw_setenv) the
configuration file /etc/fw_env.config must have both copies entries
pointing to the same offset.
This commit substitutes the hardcoded configuration file for CC6UL with a
stub and generates one on an RPM post-script basing on:
- Supplied DEY variables (with default values per platform):
- UBOOT_ENV_OFFSET: starting offset of the environment within the
partition.
- UBOOT_ENV_SIZE: size of each copy of the environment.
- UBOOT_ENV_RANGE: size in the partition that the environment copies may
occupy, starting from UBOOT_ENV_OFFSET. If undefined, the whole
partition is used.
- Calculated values:
- NAND Erase block size
- Number of blocks available for the environment copies

- Instead of using a different boot script when booting from linux
and from recovery, merge them into one script that checks the
boot source.

Patches added in 'meta-swupdate' (backported from U-Boot) broke our
layer. We also had those patches, so remove them and make sure the
rest or our patches are applied after the ones from 'meta-swupdate'
by using an anonymous python function instead of appending to the
SRC_URI variable.

On a CC6, the 'env default -a' command deletes the 'soc_family' variable
that is used on the U-Boot boot scripts to configure the name of the
device tree file to load.
Then if we try to boot into recovery directly (without a reset) because
the variable is not available, it fails to compose the correct name for
the fdt, and gives the error:
reading uImage--ccimx6sbc-id129.dtb
** Unable to read file uImage--ccimx6sbc-id129.dtb **
Force a reset, so the 'soc_family' variable is available again and the
correct fdt_file is loaded.
While on it, add some blank lines to the 'recovery reboot' message, so
it's easier to read.

The caam encryption check was only done from fw_env_write and fw_env_read
functions, which are not called when using the functions exported as a library.
Move the check_caam_encryption() call to fw_env_open(), which is called from
all code paths. A similar check for AES encryption cannot be moved because it
requires the AES key as an argument.

NAND partitions may have pre-existing UBI volume information
and that will tell U-Boot to use 'ubiwrite' to keep UBI wear
leveling information instead of erasing the NAND partition
beforehand. Given that the UBI support in U-Boot is not
particularly complete and stable, and specially if the NAND
partition table has been changed, this could result into
problems during the UBI volume initialization or during the
update process. To prevent such problems it is better that
the NAND partitions are erased.
This loses the UBI wear leveling information but provides
a more reliable deployment install script.
