Hi,
The power managment firmware, RTOSDemo-cm3.bin, linked from:
http://wiki.macchiatobin.net/tiki-index.php?page=Enable+Power+Management+on+MACCHIATObin
Does not work on 17.10 branch arm-trusted-firmware – the file format has changed. An properly formatted binary can be found from:
https://github.com/MarvellEmbeddedProcessors/binaries-marvell/tree/binaries-marvell-armada-17.10
But passing SCP_BL2=binaries-marvell/mrvl_scp_bl2_8040.img reports missing PM firmware in MSS.
Found valid image at boot postion 0x002

Also, the PM document talks about Marvell 4.4 kernel – Apart from the device tree changes, are there other bits that missing from mainline kernel to support cpuidle and cpufreq?
