From: Stanimir Varbanov <redacted> [ Upstream commit 25a98c727015638baffcfa236e3f37b70cedcf87 ] The BCM2712 memory map can support up to 64GB of system memory, thus expand the inbound window size in calculation helper function. The change is safe for the currently supported SoCs that have smaller inbound window sizes.
