+# Platform build configurations for Linaro EDK2 builds
+# ====================================================
+# The configuration file format is extremely simplistic:
+# - Each platform has a short name.
+# - A platform entry starts by the short name held in square brackets, '[]'
+# - Within each entry, all options are described in a NAME=VALUE scheme,
+#   with the name being whatever comes before the first '=' on the line,
+#   and the value being everything that comes after it.
+#
+# Mandatory options:
+# - LONGNAME		A more descriptive name of the platform.
+# - DSC			Pointer to the EDK2 build description file. (The
+#			pandaboard is excused, all other ports must have this.)
+# - ARCH		String describing the architecture to build for.
+#			Currently supported are AARCH32 and AARCH64.
+# - UEFI_BIN		Name of executable image produced.
+# - UEFI_IMAGE_DIR	Build output directory name, relative to 'Build'.
+#
+# Options for Trusted OS
+# Note that OP-TEE (https://github.com/OP-TEE/optee_os) is the only currently
+# supported Trusted OS
+# - BUILD_TOS		Set to "yes" if the build should automatically build
+#   			Trusted OS, mainly for ARM Trusted Firmware.
+#			If this is set, you must also set ATF_SPD!
+#			Else we will not know which specific Trusted OS to
+#			build.
+#			Set to "debug" to create a debug build.
+# - TOS_PLATFORM	Platform name for Trusted OS build, if
+#   			different from ARM Trusted Firmware platform
+#			or UEFI platform name.
+# - TOS_PLATFORM_FLAVOR	If a core platform has multiple flavors, specify which
+#			flavor here.
+#
+# Options for ARM Trusted Firmware platforms
+# - BUILD_ATF		Set to "yes" if the build should automatically build
+#   			ARM Trusted Firmware and a fip containing UEFI image.
+#			Set to "debug" to create a debug build.
+# - ATF_PLATFORM	Platform name for ARM Trusted Firmware build, if
+#   			different from UEFI platform name.
+# - SCP_BIN		SCP image to pass to ARM Trusted Firmware.
+# - TOS_BIN		Trusted OS image to pass to ARM Trusted Firmware.
+#			The path is relative to
+#			$EDK2_DIR/Build/$PLATFORM_IMAGE_DIR/$BUILD_PROFILE/FV/.
+#			To actually build the Trusted OS, you must also set
+#			ATF_SPD.
+# - ATF_SPD		Name of Secure Payload Dispatcher
+#			To actually build the Trusted OS, you must also set
+#			TOS_BIN.
+#
+# Optional options:
+# - BUILDFLAGS		Any special flags you want to pass to the build command.
+# - ATF_BUILDFLAGS	Any special flags you want to pass to the ARM Trusted
+#			Firmware build command.
+# - TOS_BUILDFLAGS	Any special flags you want to pass to the Trusted OS
+#			build command.
+# - EXTRA_FILES		Any additional files to be copied to output dir.
+# - PREBUILD_CMDS	Any commands you want to execute before the build step.
+# - POSTBUILD_CMDS	Any commands you want to execute after the build step.
+# - PACKAGES_PATH	Additional directories to search for packages under.
+# - INF                 Point to a .inf (in addition to a .dsc) in order to
+#                       build a single component (standalone driver/app).
