Alexei Fedorov c3e8b0be9b AArch32: Disable Secure Cycle Counter This patch changes implementation for disabling Secure Cycle Counter. For ARMv8.5 the counter gets disabled by setting SDCR.SCCD bit on CPU cold/warm boot. For the earlier architectures PMCR register is saved/restored on secure world entry/exit from/to Non-secure state, and cycle counting gets disabled by setting PMCR.DP bit. In 'include\aarch32\arch.h' header file new ARMv8.5-PMU related definitions were added.

Alexei Fedorov c3e8b0be9b AArch32: Disable Secure Cycle Counter

This patch changes implementation for disabling Secure Cycle
Counter. For ARMv8.5 the counter gets disabled by setting
SDCR.SCCD bit on CPU cold/warm boot. For the earlier
architectures PMCR register is saved/restored on secure
world entry/exit from/to Non-secure state, and cycle counting
gets disabled by setting PMCR.DP bit.
In 'include\aarch32\arch.h' header file new
ARMv8.5-PMU related definitions were added.
