# In the Xtensa architecture, assembly generates literals which must always
# precede the L32R instruction with a relative offset less than 256 kB.
# 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.*
#
# Replicate rules in scripts/Makefile.build
