+# Automatically set PACKAGE_ARCH for MACHINE_SOCARCH
+#
+# This allow to easy reuse of binary packages among similar SoCs. The
+# usual use for this is to share SoC specific packages among different
+# boards.
+#
+# MACHINE_SOCARCH_FILTER list all packages associated with
+# MACHINE_SOCARCH and, when match, will set PACKAGE_ARCH as MACHINE_SOCARCH
+#
+# MACHINE_ARCH_FILTER list all packages associated with
+# MACHINE_ARCH and, when match, will set PACKAGE_ARCH as MACHINE_ARCH
+#
+# For example, in meta-fsl-arm, this is used to share GPU packages for
+# i.MX53 boards (as all them share the AMD GPU) and i.MX6 based boards
+# (as all them share Vivante GPU).
+#
+# To use the class, specify, for example:
+#
+# MACHINE_SOCARCH_soc = "${TUNE_PKGARCH}-soc"
+#
+# and the need filters, as:
+#
+# MACHINE_ARCH_FILTER = "virtual/kernel"
+# MACHINE_SOCARCH_FILTER_soc = "virtual/libgles1 ... virtual/libgl"
