Subject: [PATCH] firmware/psci: Pass given partition number through
|
||
|
|
|
||
|
|
Pi 5 uses BL31 as its armstub file, so the reset goes via PSCI. Parse
|
||
|
|
any "reboot" parameter as a partition number to reboot into.
|
||
|
|
N.B. This code path is only used if reboot mode has been set to warm
|
||
|
|
or soft.
