On some flash (like Macronix), QE (quad enable) bit is in the same
status register as BP# bits, and we need preserve its original value
during a reboot cycle as this is required by some platforms (like
Intel ICH SPI controller working under descriptor mode).Signed-off-by: Bin Meng

The load() methods have inconsistent behaviour on error. Some of them load
an empty default environment. Some load an environment containing an error
message. Others do nothing.As a step in the right direction, have the method return an error code.
Then the caller could handle this itself in a consistent way.Signed-off-by: Simon Glass

In principle this can fail, e.g. if the index is out of range. Adjust the
driver signature to allow returning an error code.Signed-off-by: Simon Glass

This variable is declared as a global in most environment location

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.Also expand the help for the 'nowhere' option and move it to the top since
it is the default.Signed-off-by: Simon Glass

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.Signed-off-by: Simon Glass
