Micron Confidential

Hello Miquel,

Here is a short list of devices having cache read with ECC enabled.

MT29F2G08ABAGAH4, MT29F2G08ABBGAH4, MT29F2G16ABBGAH4 MT29F1G08ABAFAH4, MT29F1G08ABBFAH4, MT29F1G16ABBFAH4

Great! Thanks a lot.

It appears that even without internal ECC enabled we get failures on Micron parts, so I believe there is something else that we need to investigate. But thanks for the list, I will propose a patch preventing the use of on-die ECC together with sequential cache reads on all parts but the ones in this list (can be extended later).

Thanks, Miquèl
