[Qemu-devel] Qemu atags passing in register.

[address@hidden]

Hi,

I'm doing some tricks with Linux kernel and I'm dependent on
bootloader atags passing.

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.

Is this behaviour really OK? Isn't r2 register a proper way to pass
atags on ARM platform? If so, would you merge into mainline a patch
that implement this? I could write it, but I don't want end-users of
my work to have to patch and compile Qemu manually.

Please CC me, I'm not following actively these mailinglists.

Regards,
