+# Introduction
+U5SeriesPkg provides the common EFI library and driver modules for SiFive
+U5 series core platforms. Currently the supported platforms are Freedom
+U500 VC707 platform and Freedom U540 HiFive Unleashed platform.
+
+Both platforms are built with below common packages,
+- **U5SeriesPkg**, edk2 platform branch
+  (Currently is in edk2-platforms/devel-riscvplatforms branch)
+- **RiscVPlatformPkg**, edk2 master branch
+  (Currently is in edk2-staging/RISC-V-V2 branch)
+- **RiscVPkg**, edk2 master branch
+  (Currently is in edk2-staging/RISC-V-V2 branch)
+
+## U500 Platform
+This is a sample RISC-V EDK2 platform package used agaist SiFive Freedom U500
+VC707 FPGA Dev Kit, please refer to "SiFive Freedom U500 VC707 FPGA Getting
+Started Guide" on https://www.sifive.com/documentation.
+
+## U540 Platform
+This is a sample RISC-V EDK2 platform package used against SiFive Freedom U540
+HiFive Unleashed development board, please refer to "SiFive Freedom U540-C000
+Manual" on https://www.sifive.com.
+The binary built from Platform/SiFive/U5SeriesPkg/FreedomU540HiFiveUnleashedBoard/
+can run on main stream [QEMU](https://git.qemu.org/?p=qemu.git;a=summary)
+using qemu-system-riscv64 under riscv64-softmmu. Launch the binary with
+
+```
+-cpu sifive-u54 -machine sifive_u
+```
+
+## Download the sources
+```
+git clone https://github.com/tianocore/edk2-staging.git
+# Checkout RISC-V-V2 branch
+git clone https://github.com/tianocore/edk2-platforms.git
+# Checkout devel-riscvplatforms branch
+git clone https://github.com/tianocore/edk2-non-osi.git
+```

+Chen, Gilbert <[email protected]>
+
+## Platform Status
+Currently the binary built from U500Pkg can boot SiFive Freedom U500 VC707
+FPGA to EFI shell with console in/out enabled.
+
+## Linux Build Instructions
+You can build the RISC-V platform using below script,
+`build -a RISCV64  -t GCC5 -p Platform/SiFive/U5SeriesPkg/FreedomU500VC707Board/U500.dsc`
+
+## Supported Operating Systems
+Only support to boot to EFI Shell so far.
+
+## Known Issues and Limitations
+Only RISC-V RV64 is verified on this platform.

+## U5SeriesPkg Libraries and Drivers
+### PeiCoreInfoHobLib
+This is the library to create RISC-V core characteristics for building up
+RISC-V related SMBIOS records to support the unified boot loader and OS image.
+This library leverage the silicon libraries provided in Silicon/SiFive.
+
+### RiscVPlatformTimerLib
+This is common U5 series platform timer library which has the
+platform-specific timer implementation.
+
+### TimerDxe
+This is U5 series platform timer DXE driver whcih has the platform-specific
+timer implementation.
+
+## U500 Platform Libraries and Drivers
+### RiscVOpensbiPlatformLib
+In order to reduce the dependencies with RISC-V OpenSBI project
+(https://github.com/riscv/opensbi) and fewer burdens to EDK2 build process, the
+implementation of RISC-V EDK2 platform is leveraging platform source code from
+OpenSBI code tree. The "platform.c" under OpenSbiPlatformLib is cloned from
+RISC-V OpenSBI code tree (in EDK2 RiscVPkg) and built based on EDK2 build
+environment.
+
+### PlatformPei
+This is the platform-implementation specific library which is executed in early
+PEI phase for U500 platform initialization.
+
+## U540 Platform Libraries and Drivers
+### RiscVOpensbiPlatformLib
+In order to reduce the dependencies with RISC-V OpenSBI project
+(https://github.com/riscv/opensbi) and fewer burdens to EDK2 build process, the
+implementation of RISC-V EDK2 platform is leveraging platform source code from
+OpenSBI code tree. The "platform.c" under OpenSbiPlatformLib is cloned from
+RISC-V OpenSBI code tree (in EDK2 RiscVPkg) and built based on EDK2 build
+environment.
+
+### PlatformPei
+This is the platform-implementation specific library which is executed in early
+PEI phase for U540 platform initialization.
+
+## U5SeriesPkg Platform PCD settings
+
+| **PCD name** |**Usage**|
+|----------------|----------|
+|PcdNumberofU5Cores| Number of U5 core enabled on U5 series platform|
+|PcdE5MCSupported| Indicates whether the Monitor Core (E5) is supported on U5 series platform|
+|PcdU5UartBase|Platform serial port base address|
