I can confirm that the problem is not in the driver but in openwrt code. Dma mapping is assuming it has to shift address to pci bar no matter whether PCI is enabled or not. It seems to work on devices which don't have AHB arbitration and PCI core. Somehow dma doesn't mind that destination address with extra 0x2 at the beginning. Or at least it doesn't crash. Also physical addresses need to be consistent in platform code which is not the case at the moment. I am working now on the patch to fix it in openwrt. To get ar231x platform into the kernel is another story but if it was done for ar71xx it just matter of some effort. Actually is anyone working on it? It would allow to use platform code in the wireless driver without extensive patching.
