The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have duplicate
implementations of I/O Fifo routines. The patch series moves the I/O Fifo
routines into the BaseIoLibIntrinsic library and expands the IoLib class
to include the ported I/O Fifo routines.
The Fifo routines moved from the UefiCpuPkg/CpuIo2Dxe driver support IA32
and X64 natively, and other architectures are supported by simply looping
through the basic IoRead/IoWrite routines as appropiate.
The intent of this patch series is twofold:
1) Integrate I/O Fifo routines into the IoLib class library.
2) Allow override of IoLib as may be required to support specific hardware
implementations, such as AMD's Secure Encrypted Virtualization (SEV).
Changes since v2:
- Rework DxeIoLibEsal to use FiFo routines via the CPU I/O interfaces.
Changes only to: [PATCH v2 07/10] MdePkg/DxeIoLibEsal
