* ArmPkg/ArmArchTimerLib: correct typosEvan Lloyd2016-04-011-8/+8
| | | | | | | | | | | Some minor typographical problems were noticed during previous commits. This change corrects those, and contains no functional modifications. The changes are in comments, and one diagnostic message.

* ArmPkg/ArmArchTimerLib: fix unused variable in RELEASE buildsSami Mujawar2016-04-011-3/+2
| | | | | | | | | | | | | | | | The TimerFreq variable in the TimerConstructor() is unused in RELEASE builds since ASSERTs are then disabled. The only use of the variable (in the ASSERT) is replaced by a direct invocation of the function previously used to set it. NOTE: The build tools suppress warnings of this using compiler options eg. -Wno-unused-but-set-variable for GCC toolchain or --diag_suppress=550 for RVCT toolchain.

| | | | | | | | | | | | | | This refactors some timer code to define MultU64xN as a preprocessor symbol rather than a function pointer, and to factor out the code that obtains the timer frequency into GetPlatformTimerFreq ().

* ArmPkg: ArmArchTimerLib: conditionally rebase to actual timer frequencyLaszlo Ersek2015-02-021-20/+38
| | | | | | | | | | | | | | Allow a platform to set PcdArmArchTimerFreqInHz to zero, and consider it a request to use the actual timer frequency. No global variable is introduced, so that the library can be used in PEIMs that execute from flash.

* ArmPkg/ArmArchTimerLib: Promotes 32bit value to prevent overflowOlivier Martin2014-11-111-1/+1
| | | | | | | | | | | | | | | | Both MicroSeconds and PcdArmArchTimerFreqInHz are 32-bit values on AArch32 so their multiplication produces 32-bit result that might cause wrong calculation. Example: With MicroSeconds = 200 us, PcdArmArchTimerFreqInHz = 24MHz. 200*24000000 = 0x1_1E1A_3000 => So 0x1E1A_3000 when the type is UINT32.
