[U-Boot-Users] Redundant environment

Dear Wolfgang,

After exchanging emails with some list members, I have the feeling that there is some interest in a redundant environment implementation that is synchronized.

If I am allowed to introduce this enhancement, I pledge that existing implementations would not be effected unless CONFIG_ENV_REDUND_SYNC is defined and generated code would be virtually identical.

Of course, I will also document both behavior in README properly, introduce the same functionality in env_flash.c, env_nand.c etc. (i.e. all mediums that redundant environment is implemented) and fixup fw_setenv/fw_getenv utility.

Best regards, Tolunay
