Hello, I'm writing a small OS for ARM cortex processors and have found it greatly useful to test using qemu and the lm3s6965evb machine. The one peripheral it is missing is the flash controller. I was able to add the basic interface to mirror registers allowing to write flash words as well as erase pages. My issue is on the stellaris machine driver (hw/arm/stellaris.c) I am unable to access the rom image. I can get a pointer to the buffer using void *rom_ptr (hwaddr) but I cannot access it from the machine driver thread context. I need to be able to access this to read/write "flash" from my NOR filesystem. I will also need to XIP from that region but I'm assuming that will just work after the code has been written there.
Is there a better or right way to do this? I don't want to add a pflash peripheral because that doesn't make sense on these SOC platforms I'm targeting. Regards, Elliot
