  • Wrong env buffer was passed into sata write function, so the saveenv can't work.
    Fix this issue.

  • For multiple env drivers to correctly implement fallback when
    one environment fails to load (e.g. crc error), the return value
    of env_import has to be propagated by all env driver's load
    function.

    Without this change, the first driver that succeeds to load an
    environment with an invalid CRC return 0 (success) and no other
    drivers are checked.

  • Set up a location driver for each supported environment location. At
    present this just points to the global functions and is not used. A
    later patch will switch this over to use private functions in each driver.

    There are several special cases here in various drivers to handle
    peculiarities of certain boards:

    1. Some boards define CONFIG_ENV_IS_IN_FAT and CONFIG_SPL_ENV_SUPPORT but
    do not actually load the environment in SPL. The env load code was
    optimised out before but with the driver, it is not. Therefore a special
    case is added to env/fat.c. The correct fix (depending on board testing
    might be to disable CONFIG_SPL_ENV_SUPPORT.

    2. A similar situations happens with CONFIG_ENV_IS_IN_FLASH. Some boards
    do not actually load the environment in SPL, so to reduce code size we
    need to drop that code. A similar fix may be possible with these boards,
    or it may be possible to adjust the environment CONFIG settings.

    Added to the above is that the CONFIG_SPL_ENV_SUPPORT option does not
    apply when the environment is in flash.

    Obviously the above has been discovered through painful and time-consuming
    trial and error. Hopefully board maintainers can take a look and figure
    out what is actually needed.

  • At present we have three states for the environment, numbered 0, 1 and 2.
    Add an enum to record this to avoid open-coded values.

  • About a quarter of the files in common/ relate to the environment. It
    seems better to put these into their own subdirectory and remove the
    prefix.
