Subject: [PATCH] arm64: tegra: Add CPU and PSCI nodes for NVIDIA Tegra210
|
|
platforms
|
|
|
|
Add the CPU and PSCI nodes for the NVIDIA Tegra210 platforms so that
|
|
all CPUs can be enabled on boot. This assumes that the PSCI firmware
|
|
has been loaded during the initial bootstrap on the device before the
|
|
kernel starts (which is typically the case for these platforms). The
|
|
PSCI firmware version is set to v0.2 which aligns with the current
|
|
shipping version for Tegra.
