When booting the 5.10 kernel, I received error message: "Unhandled fault: external abort on non-linefetch (0x1028) at 0xf9e3e074".
I encountered the similar issue on the 5.4 kernel, and resolved it by disabling RTC.The cause of this issue is that our board does not use the internal RTC.

However, in the 5.10 kernel, there is no am33xx_l4_wkup__rtc, so what should I do to resolve this issue?Do you have any patch to resolve this issue?
