@matt we are booting with U-Boot. It's (roughly) ROM -> xbl_sec (el3) -> sbl1 (uart & hw init) -> tz -> hypervisor (gunyah) -> u-boot
everything before u-boot is proprietary, we are hoping to be able to optionally disable hyp and get EL2 for KVM but work will be needed (probably from the community) to get the DSPs to work in that case so we have audio
Ugh, yeah, that's unfortunate. But could be worth it, if this SoC has much better power consumption than the RK3588. Or is there some other advantage you're hoping to get out of this SoC?
