29 | * Support for persistent environment data | |
30 | * | |
31 | * The "environment" is stored as a list of '\0' terminated | |
32 | * "name=value" strings. The end of the list is marked by a double | |
33 | * '\0'. New entries are always added at the end. Deleting an entry | |
34 | * shifts the remaining entries to the front. Replacing an entry is a | |
35 | * combination of deleting the old value and adding the new one. | |
36 | * | |
37 | * The environment is preceeded by a 32 bit CRC over the data part. | |
