Commit a6485b2b

 ("refactor(delay-timer): add timer callback
functions") introduced a requirement for timer-related APIs
to have a timer object initialized before use. This caused
assertion failures in SMMU routines on Neoverse platforms,
as they relied on timer APIs.

Resolve this issue by initializing the timer early during
platform boot to set up the timer_ops object properly.

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:

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.
