PCIe memory range was arranged to 256 MB in .dts file and in U-boot configuration file. Driver was giving error with exit code -12 (OUT_OF_MEMORY). But I was able to reach the linux console. [ 5.512922] [drm] amdgpu kernel modesetting enabled. [ 5.517065] [drm] initializing kernel modesetting (POLARIS12 0x1002:0x6987 0x1787:0x2389 0x80).

I also changed 64KB I/O size to 1MB . When I do this, I wasn't able to reach the linux console because board was freezing. But driver was successfull at this time.
