So, I have not experience the breakage. However, IIUC, the GICv2m MSI 
frame is also considered DMA-able. So, I think it should be included in 
the dma-range specified here. Please let me know if my assumption is 
incorrect. Otherwise, I will include more description in the commit log 
in my next rev.

Thanks,
