Hello Peng, just a gentle ping -- did you already had a chance to check the mentioned parameter of event 0x82? Thanks in advance.

Re: [PATCH] ARM: imx: Fix parsing of ROM log event IDs on iMX8M
Hello Peng,
can you please check the parameter of event 0x82 internally? The AN12853
doesn't mention a parameter for ID 0x82, but we see something else coming
out of the bootrom of iMX8MN.
Best regards,
Fedor
