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.

Sorry for the disclaimer...it is out of my control.
