Thanks for your work.

I tested the two patches(yours and mine) separately in our environment: 
1) MXIC NFC(&raw NAND),2) MXIC SPI host(&SPI-NAND) with S/W BCH engine. 
Both patches are valid(using nandtest/nandbiterrs, values of ecc_stats are 
normal).

This seems to be because the function(nand_ecc_sw_bch_finish_io_req() 
in ecc-sw-bch.c) that would increase the ecc_stats counter is not used 
in the raw NAND world. Am I misunderstanding or is it platform dependency?

BTW, I think your modification should be more in line with the design 
spirit 
of generic ECC engine framework.

Thanks,
YouChing
