These definitions are wrong:
+#define GTDT_TIMER_SECURE EFI_ACPI_6_1_GTDT_TIMER_FLAG_ALWAYS_ON_CAPABILITY +#define GTDT_TIMER_NON_SECURE 0
+#define FVP_GTDT_GTIMER_FLAGS (GTDT_TIMER_NON_SECURE | GTDT_TIMER_ACTIVE_HIGH | GTDT_TIMER_EDGE_TRIGGERED)
Because: 1. "Table 5-118 Flag Definitions: Virtual Timer, EL2 timers, and Secure & Non-Secure EL1 timers" doesn't list security bit flags for these timers, so GTDT_TIMER_SECURE & GTDT_TIMER_NON_SECURE shouldn't exist. 2. Why is GTDT_TIMER_SECURE defined as equal to EFI_ACPI_6_1_GTDT_TIMER_FLAG_ALWAYS_ON_CAPABILITY which is BIT2? Secure Timer is BIT0 & only defined in GTx Common Flags for GT Block Timer Structure

Sorry, lost track of this one.
No objection from me, but I'd prefer a nod from Evan.
Regards,

Hi all,
I guess this patch haven't been merged yet. So do I need to fix it in anywhere or can some one help to merge it ?
Thank! :-)
