The IMX is the RC in this system. I am trying to change the BAR size on the IMX. Using the linux-imx 5.4.70, it seems that I cannot set a size to this bar, as anything I write to the BAR0 (0x10), the 1MB of size stays the same. Could you please give me a hint on how could I change this BAR, or where in the driver, size of this BAR is being set to 1MB.
