-
-1. Prefer kzalloc() over kcalloc()
-   See memory-allocation.rst which says: "to be on the safe side it's
-   best to use routines that set memory to zero, like kzalloc()"
-2. Drop dev_err() for u_boot_env_add_cells() fail
-   It can fail only on -ENOMEM. We don't want to print error then.
-3. Add extra "crc32_addr" variable
-   It makes code reading header's crc32 easier to understand / review.
