PS: Do you have any plans for PSCI support, so we can get the second core up too? I'd like to patch that in and include it in your series once my available time permits. Just thought I'd check that you/someone wasn't working on it already. :)
Let me join the PSCI discussion. This is not news, but maybe someone else didn't know it :)
There is a Linux patch that allows to bring up the second core. https://github.com/szemzoa/awboot/blob/6ea4ae4ad7a558ad952fefee1942e260aea1a...
I think this could be useful for adding PSCI support for T113.

I checked the manuals, and it seems the required bits are documented, but IIRC they differ from the other (much older) 32-bit parts. So it would require some refactoring of the existing sunxi PSCI code to accommodate the T113.
For some reason, these registers 0x070005C0, 0x070005C4, 0x070005C8 do not have a detailed description in the user manual. Only there are some notes in the paragraph '3.4.2.3 NON_CPU0 Boot Process' .
