This is not called outside of env_callback.c so mark static, remove from
<env_callback.h>

Albert ARIBAUD ef123c5253 Refactor linker-generated arrays 
Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.

Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

Nikita Kiryanov c088048533 lcd: implement a callback for splashimage 
On some architectures certain values of splashimage will lead to
a data abort exception.

Document the problem, and implement a callback for splashimage to
reject such values.

Scott Wood f8cfcf1b1c env: don't generate callback list entries for SPL 
SPL doesn't write to the environment.  These list entries prevent the
functions from being garbage-collected, even though nothing will look at
the list.  This caused several SPL builds (e.g.  P2020RDB-PC_NAND) to
break due to size limitations and/or unresolved symbols.

A static inline function is used to provide a context in which we
can consume the callback, and thus avoid unused function warnings.

Joe Hershberger 2598090b7e env: Add environment variable flags 
Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.

If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

Joe Hershberger e080d545f8 env: Add a silent env handler 
The silent variable now updates the global data flag anytime it is
changed as well as after the env relocation (in case its value is
different from the default env in such cases as NAND env)
