Hi,
We got below error print by the kernel when using eMMC RPMB on AM6548:
```

```
This could be easily triggerred with RPMB accessing, such as using mmc command to get the Write Counter:
```
mmc rpmb read-counter /dev/mmcblk1rpmb
```
The RPMB seems works with no issue, - well, at least from my testing... But this error printing is really annoying.
Any clues on what this error message is about and how to handle it?
