Subject: Re: [PATCH 1/7] remoteproc: resource table overhaul

hi Ohad

In my previous patch, to find the correct subdevice that match with 
physical memory, I used pa member of rproc_mem_entry.
but today in these 2 resources: fw_rsc_trace, fw_rsc_vdev_vring, pa 
menber has been removed.

for fw_rsc_trace it's not a problem, because use rproc_da_to_va and 
carveout feature.

but for fw_rsc_vdev_vring, I think use da member, like this.

dev = rproc_dma_find_dev(rproc, (phys_addr_t) vring->da);
va = dma_alloc_coherent(dev, size, &dma, GFP_KERNEL);
if (!va) {
	dev_err(dev, "dma_alloc_coherent failed\n");
	return -EINVAL;
}

are you OK ?
