Hello everyone, I am a trainee at STMicroelectronics France. I am working on a project "Setting up a boot chain ACPI" for STM32MPU, which is based on ARM Cortex-A . The objective of my project is to add a way of booting (with ACPI) besides Device Tree available on STM32MPU.
I found that ACPI was enabled on some x86 platforms but I don't know whether it was set up on ARM or not. I found a PATCH that discussed* Enabling ACPI booting on ARM with Raspberry Pi 4 <https://lore.kernel.org/all/20211201160315.2203099-1-...@chromium.org/T/#m3f705d5a3b59d3e58861a2f983e3d48fa20addf4> *but I don't know if it functioned or not. Did anyone here succeed in setting up ACPI on ARM by U-boot? What are the differences between x86 and ARM platforms when enabling ACPI? The architecture of my board STM32PMU is ARM so can I apply the technique used on platform x86 for my board?
