From: "Edgar E. Iglesias" <edgar.igles...@xilinx.com> Hi,
I'm looking at modeling systems where multiple CPUs co-exist with different views of their attached buses/devs. With this series I'm trying to take some steps towards having an address-space per CPU. It's not complete but good enough for making it possible to model (to some extent) CPU local memories for MicroBlaze systems in emulation mode (tcg). I'm updating the petalogix-ml605 here and will follow-up later with the petalogix-s3adsp. There is lots of future work needed, for example to transform more of the cpu_* bus accessing functions. To add more usage of AddressSpace properties to pass on address spaces to DMA models. Qtest mechanisms to target specific address spaces, etc... Cheers, Edgar Edgar E.
