+
+Build Procedure
+~~~~~~~~~~~~~~~
+
+QTI SoC expects TF-A's BL31 to get integrated with other boot software
+Coreboot, so only bl31.elf need to get build from the TF-A repository.
+
+The build command looks like
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=sc7180 COREBOOT=1
+
+update value of CROSS_COMPILE argument with your cross-compilation toolchain.
+
+Additional QTISECLIB_PATH=<path to qtiseclib> can be added in build command.
+if QTISECLIB_PATH is not added in build command stub implementation of qtiseclib
+is picked. qtiseclib with stub implementation doesn't boot device. This was
+added to satisfy compilation.
+
+QTISELIB for SC7180 is available at
+`link <https://github.com/coreboot/qc_blobs/blob/master/sc7180/qtiseclib/libqtisec.a?raw=true>`__
