bcm63xx kernel 5.10

[Daniel González Cabanelas]

Still no luck. I tested it together with the macronix patch and it
throws the same error.

[    0.936695] CPU 0 Unable to handle kernel paging request at virtual
address 0040000c, epc == 80064ff0, ra == 80066fd4
[    0.947583] Oops[#1]:
[    0.949918] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.96 #0
[    0.956087] $ 0   : 00000000 00000001 00400000 00000002
.....

Thanks for the suggestions.
Regards
