[PATCH 2/4] target/arm: Abstract the generic timer frequency

2019-11-27 Thread Andrew Jeffery
Prepare for SoCs such as the ASPEED AST2600 whose firmware configures CNTFRQ to values significantly larger than the static 62.5MHz value currently derived from GTIMER_SCALE. As the OS potentially derives its timer periods from the CNTFRQ value the lack of support for running QEMUTimers at the
