Commit Message

Lin, Meng-Bo Aug. 1, 2023, 11:22 a.m. UTC
After adding all necessary support for MSM8916 SMP/cpuidle without PSCI
on ARM32, build fortunaltezt and heatqlte device trees from the arm64
tree together with the ARM32 include to allow booting this device on ARM32.

The approach to include device tree files from other architectures is
inspired from e.g. the Raspberry Pi (bcm2711-rpi-4-b.dts) where this is
used to build the device tree for both ARM32 and ARM64.

All of SROT, or just e.g. TSENS_EN?

If only the headswitch is inaccessible, you may still reach
the hardware if it's been turned on from bl
