Also, those functions aren’t defined as WEAK so I encountered  the same problem (multiple definitions)

plat_crash_console_putc

plat_crash_console_flush

platform_mem_init

Thanks Madhukar for your answer,

I think I wasn’t so clear.

plat_setup_psci_ops is listed as mandatory in the porting guide.

I implemented it locally but linkage fails because it is also defined in arm_pm.c.

How do you suggest to avoid this multiple definition?

Thanks,

Boaz.

Hi Boaz

Yes, plat_setup_psci_ops() is mandatory. Every platform needs to implement it independently. You can use the implementation from [1] as a reference. I don’t think you have to delete any original function. If your platform does not support PSCI spec, you can implement a dummy function. Hope it helps.

int plat_setup_psci_ops(uintptr_t sec_entrypoint,

                                                const plat_psci_ops_t **psci_ops)

{

                return 0;

}

Hi all,

I have a Q about plat_setup_psci_ops()  function implementation ,

In the porting guide, that function is defined as mandatory BUT the original (arm) function isn’t defined as #pargam WEAK.

what should I do? to use/ delete the original function?

Thanks,

Boaz.
