Couple of things to note though. 1) There is a new IOMMU issue, for which I posted a fix today [1] 2) The remoteproc core still has an issue for which there is ongoing discussion [2] With these two issue taken care of, the omap remoteproc support is functional. The question though is, whether we should just wait until the above two issues are resolved and merge the DT patches post that, or merge the DT patches with status = "disabled". There aren't any boot failures without the mentioned two issues though, as one needs to enable the RPMSG_VIRTIO support before the failures really kick in (issue [2]), and this config is not enabled for OMAPs yet. Also, multi-v7 config doesn't seem to enable omap remoteproc, so that is safe also. Another thing I was considering myself was to squash all the board specific reserved-memory region patches into the dra7-ipu-dsp-common.dtsi files. However Suman wants to have these separate and as he is the actual author for these, I posted them in this form. But anyway, just so you know it would be possible to merge them together. -Tero [1] https://lore.kernel.org/linux-iommu/20200424145828.3159-1-t-kristo@ti.com/T/#u [2] https://lkml.org/lkml/2020/4/20/1094 --- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
