20 # In the Xtensa architecture, assembly generates literals which must always
21 # precede the L32R instruction with a relative offset less than 256 kB.
22 # Therefore, the .text and .literal section must be combined in parenthesis
23 # in the linker script, such as: *(.literal .text).
25 # We need to post-process the generated vmlinux.lds scripts to convert
26 # *(xxx.text) to *(xxx.literal xxx.text) for the following text sections:
27 # .text .ref.text .*init.text .*exit.text .text.*
29 # Replicate rules in scripts/Makefile.build
