Hi Everyone,
I'm working on a project with edk2, and these guys are trying to port edk2
to STM32MP25 platforms. I had no issue compiling and booting the image on
my device. Then I've come across an issue at very early stages of booting.
I was given a Synchronous Exception listed briefly below.

By using objdump to determine where the wrong source code is, I found out
that the program stopped around the code below.
UINT32
EFIAPI
MmioRead32 (

UINT32 Value;

ASSERT ((Address & 3) == 0);
Flag = FilterBeforeMmIoRead (FilterWidth32, Address, &Value);

} else {
Value = *(volatile UINT32 *)Address;
}
MemoryFence ();
}
FilterAfterMmIoRead (FilterWidth32, Address, &Value);

The fault address is 0x00000004AC100004. Is that in the address range of the GIC for this platform? What does that Physical address map to you on the STM32MP25?
Thanks,
Andrew Fish
