The best would be to find two which are exactly next to each other so
you can short circuit them with a knitting needle or similar.
When you flash a new barebox to NOR flash make sure you flash one that
doesn't get its environment from NAND, so comment out the following
lines in the board file:
devfs_del_partition("env_raw");
devfs_add_partition("nand0", 0x40000, 0x20000, DEVFS_PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");
