From 09bd08401a5ff2cdbf40fdc27a8add809ae11075 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 3 Feb 2021 21:22:40 +0800 Subject: serial: ns16550: Correct the base address type Currently ns16550_serial_assign_base() treats the argument 'base' with type `ulong`. This is incorrect because the base address was obtained from device tree with type `fdt_addr_t` that can represent a physical address larger than 32-bit in a 32-bit system.
