+# HPS Content Wipe Program
+
+The HPS content wipe program is a small program that is invoked by SDM when there is a security breach event detected or during a cold reset. The intention of this program is to clear HPS content, especially in cache. This memory might contain sensitive data.
+
+## How to build
+User can build the HPS wipe with two different compilers, which are GCC and ARMCLANG
+
+### GCC compiler 
+> $make COMPILER=GCC 
+
+User can specify the CROSS_COMPILE option, since in linaro version 9, the binary name of the compiler changed.
+> $make COMPILER=GCC  CROSS_COMPILE=aarch64-linux-gnu-
+> $make COMPILER=GCC  CROSS_COMPILE=aarch64-none-linux-gnu-
+
+### ARMCLANG Compiler
+> $make COMPILER=ARMCLANG
+
+## To clean
+> $make clean COMPILER=GCC
+> $make clean COMPILER=ARMCLANG
+
+
+## Prerequisite
+### Compile with GCC
+Please download GCC compiler from
+https://releases.linaro.org/components/toolchain/binaries/7.5-2019.12/aarch64-linux-gnu/
+
+### Compile with ARMCLANG
+Please download ARM Development Studio from
+https://www.arm.com/
+
+### For Windows user
+Please download MSYS2 from
+https://www.msys2.org/
+
+### Export Environment
+Please export the installation path of the bin folder for the compilers
+Examples:
+
+GCC
+> export PATH=$PATH:/c/gcc-linaro-7.5.0-2019.12-i686-mingw32_aarch64-linux-gnu/gcc/bin
+
+ARMCLANG
+> export PATH=$PATH:/c/Program\ Files/Arm/Development\ Studio\ 2021.0/sw/ARMCompiler6.16/bin
