Subject: [PATCH 09/13] sunxi: Enable support for SCP firmware on H3
|
|
|
|
Now that issues with the BROM have been sorted out, we can implement
|
|
PSCI system suspend on H3 by delegating to SCP firmware. Let's start by
|
|
including the firmware in the FIT image and starting the coprocessor if
|
|
valid firmware is loaded.
