Hi Przemyslaw,
> This change allows updating environment stored on MMC by dfu or thor.
>
> New setting:
> - "params.bin mmc 0x38 0x8"
>
> File params.bin can be generated by: tools/mkenvimage.
> e.g. ./mkenvimage -s 4096 -o params.bin <env_text_file>
>
> Every new env variable in text file should start with a new line.
>
> Sample env text file:
> - board/samsung/common/dfu_sample_env.txt
>
> Requirements:
> - file name: "params.bin"
> - file size: 4096 Bytes - the same as CONFIG_ENV_SIZE.
> Other size will cause CRC miscalculation at boot.
