From 18416ba1198afaae10b91552e8b0024cb84de2fa Mon Sep 17 00:00:00 2001 From: "Park, Aiden" Date: Wed, 18 Dec 2019 05:56:23 +0000 Subject: x86: serial: Use NS16550_DYNAMIC in Slim Bootloader Slim Bootloader provides serial port info in its HOB to support both IO or MMIO serial ports, but it's controlled by SYS_NS16550_MEM32 or SYS_NS16550_PORT_MAPPED in U-Boot. To support both serial port configurations dynamically at runtime, Slim Bootloader serial driver leverages NS16550_DYNAMIC.
