When a variable with a registered callback is inserted, deleted, or
overwritten the callback is called and gives the system an opportunity
to do something in response to the change. It also has the opportunuty
to reject the change by returning non-zero.
Before I go much further, I want to get a little feedback if this is a
good implementation. It certainly cleans up cmd_nvedit.c significantly!
Joe Hershberger (5):
env: Add support for callbacks to environment vars
env: Add a loadaddr env handler
env: Add a bootfile env handler
env: Add a baudrate env handler
env: Add a console env handler
