[Qemu-devel] Prop-ptr and Xilinx.

[Peter Crosthwaite]

Hi Paolo,

Im testing your revisions the the xilinx ip around getting rid of the
pointer props (your prop-ptr branch on your github).

First up theres a typo in the machine model stuff, heres the fix:

diff --git a/hw/petalogix_ml605_mmu.c b/hw/petalogix_ml605_mmu.c
index 37866f4..e718183 100644
--- a/hw/petalogix_ml605_mmu.c
+++ b/hw/petalogix_ml605_mmu.c

     xilinx_timer_create(TIMER_BASEADDR, irq[2], 2, 100 * 1000000);

     /* axi ethernet and dma initialization. */
-    DeviceState *dma = qdev_create(NULL, "xilinx-axidma");
+    DeviceState *dma = qdev_create(NULL, "xilinx,axidma");
     DeviceState *eth0;

     eth0 = xilinx_axiethernet_create(&nd_table[0], XILINX_AXIDMA_PEER(dma),

I corrected this and ran it but SIGABRT'ed on some assertion in the
qom framework:
