Normally barebox stores the environment on the medium it is started
from. Looking at arch/arm/boards/phytec-phycore-omap4460/board.c:
#ifdef CONFIG_PARTITION
devfs_add_partition("nand0", 0x00000, SZ_128K, DEVFS_PARTITION_FIXED, "xload_raw");
dev_add_bb_dev("xload_raw", "xload");
devfs_add_partition("nand0", SZ_128K, SZ_512K, DEVFS_PARTITION_FIXED, "self_raw");
dev_add_bb_dev("self_raw", "self0");
devfs_add_partition("nand0", SZ_128K + SZ_512K, SZ_128K, DEVFS_PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");
#endif
The last two lines create /dev/env0 on nand. If you boot from nand the
environment should be stored there already.
