Passing the memory base address still allows the bootloader to fill the memory size. Signed-off-by: Fabio Estevam <redacted>
One thing I'm unsure is which memory node will be fixed up with correct
memory configuration, considering we will have two memory nodes. One is
the following that defined in imx51.dtsi.
memory { device_type = "memory"; };
And the other is memory at 90000000.
