# 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 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/
