bcm63xx kernel 5.10

[Hauke Mehrtens]

Hi,

We would like to switch the bcm63xx target to kernel 5.10. Paul created 
a pull request for that:
https://github.com/openwrt/openwrt/pull/4616

There is still a problem with Macronix NAND flash chips, see the 
comments from the pull request.

Could someone please have a look into this problem.

Does this change in the upstream kernel help?
