See my original query, which IMO disproves that assertion. What this option enables differs in two ways from what the MontaVista code does. (Speaking here of the 1-bit HW ECC. The 4-bit support is another mess, which would be made far worse by needing to carry the BROKEN_ECC mode.) One could define a MONTAVISTA_COMPAT option, but it would not AFAICT be this BROKEN_ECC since it would only differ from the current Linux code in *one* of those three ways. (Which has in turn also been claimed to be broken, by mis-reporting some multi-bit errors as single-bit ones.) Which is why I'm wondering what that original U-Boot code for HW ECC was trying to be "compatible" with, since it clearly wasn't MontaVista Linux ... or even the U-Boot versions I've seen be distributed with it. - Dave _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
