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

OpenEmbedded/Yocto BSP layer for Digi's ConnectCore platforms ============================================================= This layer provides support for Digi's ConnnecCore platforms for use with OpenEmbedded and/or Yocto. This layer depends on: git://git.yoctoproject.org/poky.git git://git.openembedded.org/meta-openembedded.git git://git.yoctoproject.org/meta-freescale.git Digi's license agreements ------------------------- All software is covered by Digi's general EULA and Digi's Open Source EULA. To have the right to use the software in your images you need to read and accept both EULAs at the DIGI_EULA and DIGI_OPEN_EULA files. NXP Semiconductors' software license agreement ---------------------------------------------- Some platforms depends on libraries and packages that are covered by NXP Semiconductors' EULA. To have the right to use those binaries in your images you need to read and accept the EULA file in meta-freescale Yocto layer. Support ------- This layer is provided 'as is' with no guarantee. However, some support may be available from support@digi.com
