+Bootrom --> BL1/BL2 --> BL31 --> BL33 --> Linux kernel
+
+BL1/2 and BL33 can currently be supplied from Coreboot + Depthcharge
+
+How to build
+------------
+
+Code Locations
+~~~~~~~~~~~~~~
+
+- Trusted Firmware-A:
+ `link <https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git>`__
+
+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://review.coreboot.org/cgit/qc_blobs.git/plain/sc7180/qtiseclib/libqtisec.a>`__
