Applied this on next-20220602 (with a few fixes for other section mismatch
errors), booted and got:
[ 1.948483] mtk-devapc 10207000.devapc: Read Violation

during the boot process. So I think this works well. Manually reading a
known secure address also triggers it:
root@hayato:~# busybox devmem 0x1000e000
0x00000000
[ 135.069121] mtk-devapc 10207000.devapc: Read Violation
[ 135.069132] mtk-devapc 10207000.devapc: Bus ID:0x482, Dom ID:0x0,
Vio Addr:0x1000e000
So,
Tested-by: Chen-Yu Tsai <wenst@chromium.org>
BTW, looks like MT8186 support in mainline is shaping up real good.
SCP firmware is still missing, so video codec stuff won't work.
