2012-12-22env: don't generate callback list entries for SPLScott Wood
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.

2012-12-13env: Add environment variable flagsJoe Hershberger
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. Signed-off-by: Joe Hershberger <[email protected]>
2012-12-13env: Add a silent env handlerJoe Hershberger
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) Signed-off-by: Joe Hershberger <[email protected]>
