[edk2-devel] [PATCH v2 1/1] MdeModulePkg: BaseSerialPortLib16550: Add missing Pcd to UNI

[Loh, Tien Hock]

From: "Tien Hock, Loh" <tien.hock.loh at intel.com>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1771

Some busses doesn't allow 8 bit MMIO read/write, this adds support for
32 bits read/write. This patch adds the UNI information on the new Pcd
introduced - PcdSerialRegisterAccessWidth
