Subject: [PATCH v3 01/10] MdePkg: Expand BaseIoLibIntrinsic (IoLib class) library
Date: Fri, 13 Jan 2017 14:09:51 -0600	[thread overview]
Message-ID: <1484338200-31337-2-git-send-email-leo.duran@amd.com> (raw)
In-Reply-To: <1484338200-31337-1-git-send-email-leo.duran@amd.com>

The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have duplicate
implementations of I/O Fifo routines. This patch clones the I/O Fifo
routines into the BaseIoLibIntrinsic library and expands the IoLib class
to include the ported I/O Fifo routines.
