+ bool "env callbacks - print callbacks and their associated variables"
+ help
+ Some environment variable have callbacks defined by
+ U_BOOT_ENV_CALLBACK. These are called when the variable changes.
+ For example changing "baudrate" adjust the serial baud rate. This

+config CMD_ENV_FLAGS
+ bool "env flags -print variables that have non-default flags"
+ help
+ Some environment variables have special flags that control their
+ behaviour. For example, serial# can only be written once and cannot
+ be deleted. This command shows the variables that have special
+ flags.
