This patchset modifies the handling of all the operations on the environment (set/import/default) so to unify handling of special variables. On top of that we implement a selective "env default".
A selective "env import" would imply a user API change and should therefore be discussed separately.
Changes in the syntax (user API): - "env default" -f: override write-once variables, -a means all
Changes from v1: - removed cosmetic patches (now mainstream) - rebased to latest trunk - removed subtle error in env_check_apply (comparing {loadaddr, bootfile} to values instead of variable names) - changed env_check_apply so not to display warnings in case of H_FORCE flag being set
Changes from v0 - checkpatch cleanup - removed himport_ex() - removed warning for serial_assign() - env import NOT implemented here
Gerlando Falauto (3): env: unify logic to check and apply changes env: check and apply changes on delete/destroy env: make "env default" selective, check and apply
