On PandaBoard the u-boot is always passing DTF/Atags pointer in r2 register, and I'm kind of depending on it. I need to emulate this behavior by -initrd qemu's argument. However it seems that qemu-system-arm zeros the registers on the start, and places atags in some hardcoded memory address no matter what.
No, qemu will correctly pass the atags in r2 if it is booting a linux kernel (ie if you pass it a non ELF file via the -kernel argument). Otherwise we wouldn't be able to boot Linux. How are you starting qemu ?
