meta-tpm layer
==============
+The bbappend files for some recipes (e.g. linux-yocto) in this layer need
+to have 'tpm' in DISTRO_FEATURES to have effect.
+To enable them, add in configuration file the following line.
+
+ DISTRO_FEATURES_append = " tmp"
+
+If meta-tpm is included, but tpm is not enabled as a
+distro feature a warning is printed at parse time:
+
+ You have included the meta-tpm layer, but
+ 'tpm' has not been enabled in your DISTRO_FEATURES. Some bbappend files
+ and preferred version setting may not take effect.
+
+If you know what you are doing, this warning can be disabled by setting the
following
+variable in your configuration:
+
+ SKIP_META_TPM_SANITY_CHECK = 1
+
+
This layer contains base TPM recipes.
