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/6ea4ae4ad7a558ad952fefee1942e260aea1a69f/linux/second_core_support_in_platsmp.patch#L10 I think this could be useful for adding PSCI support for 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' .
