[PATCH 0/3] env: sf: add support of command env erase

[Patrick Delaunay <patrick.delaunay@foss.st.com>]

Hi,

I add support of env erase command for SPI flash backend (sf).

To erase the environment, this patch only invalidate the content at
CONFIG_ENV_OFFSET and at CONFIG_ENV_OFFSET_REDUND (force a bad CRC).

The 2 first patchs of the serie are preliminary and clenaup steps.

Patrick
