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
