[U-Boot] nand_spl/nand_boot.c: why can't we do anything on ECC error?

[Jens Gehrlein <sew_s@tqs.de>]

Hi,

in nand_spl/nand_boot.c in function nand_read_page() one can read the 
comment in the case of ECC errors:
"No chance to do something with the possible error message from 
correct_data(). We just hope that all possible errors are corrected by 
this routine."

Why can't we do anything? If an uncorrectable error has been recognized, 
we could at least execute an endless loop or issue a reset. Depending on 
the bit errors and their location in the U-Boot image, U-Boot may though 
boot and a runtime error could probably appear never or later or only 
under special circumtances. Because this is a risk (the image is 
corrupted), what do you think of inserting some blocking functionality?

Or did I missed something in interpreting this code?

Kind regards,
Jens
