# environment sector is assumed present.
fw_env: calculate default number of env sectors The assumed number of environment sectors (always 1) leads to an incorrect top_of_range calculation in fw.env.c when a flash device has an erase block size smaller than the environment data size (number of environment sectors > 1). This change updates the default number of environment sectors to at least cover the size of the environment. Also corrected a false statement about the number of sectors column in fw_env.config.

# Notice, that the "Number of sectors" is not required on NOR and SPI-dataflash.
Various, unrelated tree-wide typo fixes. Fix a number of typos, including: * "compatble" -> "compatible" * "eanbeld" -> "enabled" * "envrionment" -> "environment" * "FTD" -> "FDT" (for "flattened device tree") * "ommitted" -> "omitted" * "overriden" -> "overridden" * "partiton" -> "partition" * "propogate" -> "propagate" * "resourse" -> "resource" * "rest in piece" -> "rest in peace" * "suport" -> "support" * "varible" -> "variable" Signed-off-by: Robert P.

Add support for dataflash to U-boot environment settings tool. * The sector size for SPI-dataflash (like AT45 flashes) are not always a power-of-2. So, the sector calculations are rewritten such that it works for either power-of-2 as any size sectors. * Make the flash sector size optional in case it is the same value as the environment size.

tools: env: Add support for direct read/write UBI volumes Up to now we were able to read/write environment data from/to UBI volumes only indirectly by gluebi driver. This driver creates NAND MTD on top of UBI volumes, which is quite a workaroung for this use case. Add support for direct read/write UBI volumes in order to not use obsolete gluebi driver.
