+Trusted Firmware-A for QEMU SBSA target
+========================================
+
+Trusted Firmware-A (TF-A) implements the EL3 firmware layer for QEMU SBSA
+Armv8-A. While running Qemu from command line, we need to supply two Flash
+images. First Secure BootRom is supplied by -pflash argument. This Flash image
+is made by EDK2 build system by composing BL1 and FIP. Second parameter for Qemu
+is responsible for Non-secure rom which also given with -pflash argument and
+contains of UEFI and EFI variables (also made by EDK2 build system). Semihosting
+is not used
+
+When QEMU starts all CPUs are released simultaneously, BL1 selects a
+primary CPU to handle the boot and the secondaries are placed in a polling
+loop to be released by normal world via PSCI.
+
+BL2 edits the FDT, generated by QEMU at run-time to add a node describing PSCI
+and also enable methods for the CPUs.
+
+Current limitations:
+
+-  Only cold boot is supported
+-  No instructions for how to load a BL32 (Secure Payload)
+
+To build TF-A:
+
+::
+
+    git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git tfa
+    cd tfa
+    export CROSS_COMPILE=aarch64-linux-gnu-
+    make PLAT=qemu_sbsa all fip
+
+Images will be placed at build/qemu_sbsa/release (bl1.bin and fip.bin).
+Need to copy them into top directory for EDK2 compilation.
+
+::
+
+    cp build/qemu_sbsa/release/bl1.bin ../
+    cp build/qemu_sbsa/release/fip.bin ../
+
+Those images cannot be used by itself (no semihosing support). Flash images are built by
+EDK2 build system, refer to edk2-platform repo for full build instructions.
+
+::
+
+    git clone https://github.com/tianocore/edk2-platforms.git
