When storing u-boot environment variables on a NOR flash using multiple sectors, the following error occurs when writing changes using fw_setenv.

/etc # cat fw_env.config

/dev/mtd12 0x0000 0x20000 0x10000 2

/etc # fw_setenv test test

End of range reached, aborting

Error: can't write fw_env to flash

The reason for the error is that although both sectors are written in one pass, the loop for the write is executed twice because the "processed" variable is incremented by the incorrect amount.
