Current DP implementation depends on TimerLib, as different platforms may implement and use their own TimerLib, it makes the dp needs to be built by platform. The TimerLib dependency can be removed by using performance property configuration table to make DP to be generic.
There was a discussion on edk2-devel about supporting use of different TimerLib instances in different modules and updating the performance log to support measurements with different timer rates. A complete solution for this has not been found. This patch series that allows the DP command to get the timer rate from a system configuration table is useful on its own because it allows the DP shell command to be independent of the TimerLib used to collect the performance logs. V3: Define and install performance property configuration table instead of extending PEI performance log HOB. As user may want to only dump DXE or SMM performance data, then PeiPerformanceLib will be not linked and PEI performance log HOB will be not built. V4: Change name of field in PERFORMANCE_PROPERTY from CpuFreq to Frequency.
