Hotplug poweron is not working for boot CPU as it's being triggerred using PMC and not with Flow Controller. This is happening because "cpu_powergate_mask" is only getting set for non-boot CPU's as the boot CPU's first bootup follows different code path. The patch is marking a CPU as ON within "cpu_powergate_mask" when turning its power domain on during power on. This will ensure only first bootup on all CPU's is using PMC and subsequent hotplug poweron will be using Flow Controller.

Trusted Firmware-A
Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.
TF-A implements Arm interface standards, including:
- Power State Coordination Interface (PSCI)
- Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)
- SMC Calling Convention
- System Control and Management Interface (SCMI)
- Software Delegated Exception Interface (SDEI)
The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.
In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.
Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
