[PATCH 2/2] WIP: arm64: dts: mt8189: Add mt8189 dts evaluation board and Mafefile

Mon May 5 05:15:46 PDT 2025


MT8189 is a SoC based on 64bit ARMv8 architecture. It contains 6 CA55
and 2 CA78 cores. MT8189 share many HW IP with MT8188 series.

We add basic chip support for MediaTek MT8189 on evaluation board.

BUG=b:387230785
TEST=emerge-skywalker chromeos-kernel-6_6
