For x86 I am able to use -initrd to load an additional ramdisk alongside my kernel.

I am now working on ARM (-machine integratorcp) and I have a bit of problem understanding what data QEMU should provide to my kernel about where it has placed the ramdisk. When I look through the QEMU code it seems like it is suppose to provide the kernel with a table filled with ATAGS both at base + 0x100 and in register r2 but that does not seem to be the case.

Has anyone had any luck getting this to work? In that case what did you do?

I use it on the r-pi target (non-mainstream) which always puts it at 128M or halfway up the memory, which for all RPIs is 128M. No idea if there's any other way to find out where it is, I just looked up the location in the qemu sources and called it a day as it's a development-time only thing anyway for me.
