I am working with QEMU to simulate VersatilePB board.
I am trying to understand how QEMU initialize the virtual peripherals (e.g.
UART, vectored Interrupt controller .. etc).
When I traced the code, I found a function called "object_init_with_type"
in object.c, in which the function pointer "ti->instance_init(obj)" seems
to call the peripherals initialization functions.
*I have couple of questions here:*
1.) Some peripheral initialization functions are called multiple times such
as pl011_init, why is that ?
2.) Where is the entry point for the whole initialization functionalities
(that will eventually call "object_init_with_type")
