From: Dick Olsson <hi@senzilla.io>

This introduces a configuration for the SBSA reference machine under QEMU that
is intended for developing and testing firmware. It consists of ATF that load
EDK2 as BL33 which in turn will load the kernel in EFI stub mode with ACPI.

Revision 2:

 * This board was renamed/moved to be specific for QEMU sbsa-ref
 * General simplification
 * Using set -e in the post-images.sh script

+Intro
+=====
+
+The QEMU sbsa-ref machine is primarily meant for firmware development and
+testing. Thus, the Linux kernel is not necessarily meant to boot to userland.
+
+A successful boot should be considered:
+
+1. ARM Trusted Firmware (ATF) boots until BL31
+2. ATF loads EDK2 (UEFI) as BL33
+3. EDK2 loads the Linux kernel in EFI stub mode
+4. Linux begins to boot, exits boot services, begins loading the address map
+5. Freez
+
+Build
+=====
+
+  $ make qemu_aarch64_sbsa_defconfig
+  $ make
+
+Emulation
+=========
+
+Run the emulation with:
+
+  qemu-system-aarch64 \
+    -M sbsa-ref \
+    -cpu cortex-a57 \
+    -smp 4 \
+    -m 1024 \
+    -nographic \
+    -drive file=output/images/SBSA_FLASH0_RESIZED.fd,if=pflash,format=raw \
+    -drive file=output/images/SBSA_FLASH1_RESIZED.fd,if=pflash,format=raw \
+    -hda output/images/disk.img
