The test is not called from any of the setup functions, so there's no reason keeping it in the setup.c. Move it to s32c1i_selftest.c and drop related #include directives. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

# 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
