handoff data

[Renaud Barbier]

On our LS1046A based board (v2022.03) we used to pass the results of memory tests in the PBL  through the OCRAM to the barebox load.
I see there is handoff data support.

In my board lowlevel.c code, I have added the call:

handoff_add_arm_machine(0x12345678);


And then try to read it back from device_initcall:

 machine = handoff_data_get_entry(HANDOFF_DATA_ARM_MACHINE, &hsize);
printf("machine = %ld, %p\n", hsize, machine);

However, both the machine pointer and size are set to 0.

Am I missing something in the process?

Cheers,
Renaud
