64-bit ARM With Linux 6.10: Building FIT Images & Optional Disabling 32-bit User-Space
Merged last week for the Linux 6.10 kernel were all of the 64-bit ARM (ARM64 / AArch64) architecture changes
ARM64 now supports Firmware ACPI Control Structure (FACS) signature feature that is necessary to reboot out of hibernation on some hardware. FACS stores the hardware signature at last boot, a global lock to synchronize access to shared hardware resources between the OSPM and external controller environment, the OSPM's Waking Vector, and other data can be found within the FACS table. Flat Image Trees is a compiled Linux kernel paired with the associated DeviceTree that is compressed and then easily distributed.
