Nicolas Saenz Julienne 0634a2dc95 ARM: dts: bcm2711: fix soc's node dma-ranges ... Raspberry Pi's firmware has a feature to select how much memory to reserve for its GPU called 'gpu_mem'. The possible values go from 16MB to 944MB, with a default of 64MB. This memory resides in the topmost part of the lower 1GB memory area and grows bigger expanding towards the begging of memory. It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of the memory available to the system in the lower 1GB area can outgrow the interconnect's dma-range as its size was selected based on the maximum system memory available given the default gpu_mem configuration. This makes that memory slice unavailable for DMA. And may cause nasty kernel warnings if CMA happens to include it. Change soc's dma-ranges to really reflect it's HW limitation, which is being able to only DMA to the lower 1GB area.
