Hi Marc,

Yes, only affect "can: flexcan: add CAN wakeup function for i.MX8", I will remove this patch first.
Sorry, I replied in a wrong place.

"can: flexcan: initialize all flexcan memory for ECC function" for this patch, I find this issue in i.MX8MP, which is the first SoC implements ECC for i.MX
I think this patch should compatible with others which has ECC support, but I don't have one to have a test.

Best Regards,
Joakim Zhang
