[PATCH v4 00/14] env: ext4: corrections and add test for env in ext4

[Patrick Delaunay]

Hi,

V4 of the serie [1]: rebase on master branch and solve the SPL size
issue for board with SPL_ENV_IS_NOWHERE=y (pointed by Tom Rini in [2])

The buildman result for these boards are:

-------------------------------------------------

In this serie, I add sandbox test with CONFIG_ENV_IS_NOWHERE
activated with EXT4 location: load, save and erase.

To test this feature, I add 2 new commands to change the
ENV location:
- env select [target]
- env load

To be able to test invalid file (bad CRC), I also add the support of
the command "env erase" for EXT4 env location.

Changes in v4:
- don't use env_import in SPL to avoid to increase its size
  as it is only required for 'env load' command

Changes in v3:
- new
- new
- new: add load ops in nowhere
- new: load operation becomes mandatory
- new: add 'env load' command
- new: add 'env select' command
- change env_get_location to avoid gd->env_load_prio modification
- replace specific sandbox command by generic command
  'env select' and 'env load'
- change title "sandbox: support the change of env location"
- replace specific sandbox command by generic command
  'env select' and 'env load'
- update after Stephen Warren comments
- replace sandbox command by generic command 'env load' in test_env

Changes in v2:
- change cmd_tbl_t to struct cmd_tbl
- use CONFIG_IS_ENABLED to set .erase (same as .save)
