[v12] Add support for RaspberryPi RP1 PCI device using a DT overlay

[PATCH v12 12/13] arm64: defconfig: Enable OF_OVERLAY option

Posted by Andrea della Porta 6 months, 3 weeks ago

The RP1 driver uses the infrastructure enabled by OF_OVERLAY config
option. Enable that option in defconfig in order to produce a kernel
usable on RaspberryPi5 avoiding to enable it separately.
