lack of delay function in library

[chinamao]

hi, experts:
Is there any plan to implement a common delay function based on generic timer?

best wishes,

The current codebase does not use the generic timers, other than initialization of the system counter clock frequency*. There is currently no plan for BL3-1 (the EL3 runtime firmware) to use the secure physical timer other than to:
a) Allow BL3-2 (the Secure Payload) to have access to it, or
b) (Possibly) manage context save/restore of the EL1 physical timer in cases where this has to be shared between the normal world and BL3-2.

So there's currently no plan to add general purpose library functions like "delay".

• This is currently incorrectly done in architectural code instead of platform code (see bl1_arch_setup() should not program the counter frequency #24).
