drivers/dma/pl330.c needs also a successfully matched amba, but this fails when using mainline TF-A and U-Boot SPL. I'm using the same kernel and devicetree on both tests, the only thing changed is TF-A and U-Boot SPL vs mini-loader and rk3399_bl31. > This driver should has nothing to do with U-Boot SPL or TF-A, because we > don't have any special setting for PL330 in loader stage. It is drivers/amba/bus.c, which is unable to find an AMBA_CID on the ARM bus. The DMA driver not loading is just a symptom of this issue. Any ideas? Thanks -- Christoph
