This was pointed out with the recent name change of or32_early_setup to

so cleaning them up here.

arch/openrisc/kernel/setup.c:220:13: warning: no previous prototype for 'or1k_early_setup' [-Wmissing-prototypes]
220 | void __init or1k_early_setup(void *fdt)
| ^~~~~~~~~~~~~~~~

Fix this the missing or1k_early_setup prototype warning by adding an
asm/setup.h file to define the prototype.

arch/openrisc/kernel/setup.c:246:13: warning: no previous prototype for 'detect_unit_config' [-Wmissing-prototypes]
246 | void __init detect_unit_config(unsigned long upr, unsigned long mask,
| ^~~~~~~~~~~~~~~~~~

The function detect_unit_config is not used, just remove it.

arch/openrisc/kernel/setup.c:221: warning: Function parameter or member 'fdt' not described in 'or1k_early_setup'

Add @fdt docs to the function comment to suppress this warning.

Hi Stafford,

Does this patch apply to your openrisc tree, but not to
linux-next? I get a patch error when trying to apply it
to linux-next-20210805 and this warning is still present:

../arch/openrisc/kernel/setup.c:221:13: warning: no previous prototype for 'or32_early_setup' [-Wmissing-prototypes]
221 | void __init or32_early_setup(void *fdt)
| ^~~~~~~~~~~~~~~~

presumably because some openrisc patches are not yet in linux-next??

thanks.
