[U-Boot] [PATCH v4 0/4] add command env erase

[Frank Wunderlich]

sometimes it is needed to erase the non-volatile environment
e.g. for boot-up with builtin-environment or after resizing env

this series add basic functionality for erasing environment from storage
as a first storage-driver mmc is introduced, other needs to be added later

changes since v3:
 - fixes
 - Kconfig-option as suggested by Simon Goldschmidt
 - including CONFIG_ENV_OFFSET_REDUND (4/4 is RFC)

Frank Wunderlich (4):
  env: register erase command
  env: mmc: add erase-function
  env: add option to use redundant offset
  [RFC] env: call env_erase twice if CONFIG_ENV_OFFSET_REDUND is set
