Actually, I need to enable VDDIO3/4 even earlier, otherwise I get no 
UART and no I2C, so that's not a problem. VDDIO3/4 handling seems to be 
broken in the ST downstream TFA with almost 1000 patches on top of old 
version of TFA, and upstream TFA for STM32MP25xx is entirely bare bones 
that it barely works.

I also didn't manage to start upstream U-Boot on STM32MP25xx at all yet, 
I still have to upport about 400 patches (reduced from some 800 from ST 
downstream old U-Boot fork), and the result won't work unless I use the 
obsolete ST downstream OpTee-OS 4.0 fork with almost 1700 patches on top.

Maybe the upstream OpTee-OS is missing something, like the entire SCMI 
implementation ?
