Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase frame of the system timer. ARM ARM states that "The instance of the register in the CNTCTLBase frame must be programmed with this value as part of system initialization." The psci_arch_setup() updates the CNTFRQ system register but according to the ARM ARM, this instance of the register is independent of the memory mapped instance. This is only an issue for Normal world software which relies on the memory mapped instance rather than the system register one. This patch resolves the issue for ARM platforms. The patch also solves a related issue on Juno, wherein CNTBaseN.CNTFRQ can be written and does not reflect the value of the register in CNTCTLBase frame. Hence this patch additionally updates CNTFRQ register in the Non Secure frame of the CNTBaseN.
