Subject: [PATCH RFC 0/2] firmware: ti_sci: Introduce BOARDCFG_MANAGED mode
 for Jacinto family

This series introduces the BOARDCFG_MANAGED mode, which is used by the
Jacinto family. In this mode, low power configuration is handled
statically for the Device Manager (DM) via boardcfg.
On Jacinto SoCs, the DM-Firmware does not support suspend-resume; instead,
it is restarted from scratch during resume. As a result, the firmware is
unable to restore IRQs, and this responsibility is delegated to the ti_sci
driver.
