+# In the Xtensa architecture, assembly generates literals which must always

+# Therefore, the .text and .literal section must be combined in parenthesis
+# in the linker script, such as: *(.literal .text).
+#
+# We need to post-process the generated vmlinux.lds scripts to convert
+# *(xxx.text) to *(xxx.literal xxx.text) for the following text sections:
+# .text .ref.text .*init.text .*exit.text .text.*
