These defines have been present since the initial git import in commit 1da177e4c3f4 ("Linux-2.6.12-rc2"). They predate the modern Kconfig convention that CONFIG_ prefixed symbols should always originate from Kconfig. The third define on the same line, SCSI_NCR_BIG_ENDIAN, already correctly omits the CONFIG_ prefix. The CONFIG_ prefix is misleading: these are not user-configurable options and do not appear in any Kconfig menu. They are unconditionally enabled for all Zalon builds. Remove the CONFIG_ prefix from both symbols — renaming them to NCR53C8XX_PREFETCH and SCSI_NCR53C8XX_NO_WORD_TRANSFERS — to match the convention used by SCSI_NCR_BIG_ENDIAN on the same line and to avoid confusion with actual Kconfig-managed symbols. No functional change.

kconfiglint reports:

  X001: CONFIG_NCR53C8XX_PREFETCH referenced in Makefile but not
        defined in any Kconfig
  X001: CONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS referenced in Makefile
        but not defined in any Kconfig

The ncr53c8xx SCSI driver uses two preprocessor defines that carry the
CONFIG_ prefix but are not defined in any Kconfig file:

  -DCONFIG_NCR53C8XX_PREFETCH
  -DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

These are hardcoded compiler flags in drivers/scsi/Makefile, passed only
when CONFIG_SCSI_ZALON is enabled:

  ncr53c8xx-flags-$(CONFIG_SCSI_ZALON) \
      := -DCONFIG_NCR53C8XX_PREFETCH -DSCSI_NCR_BIG_ENDIAN \
          -DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

The source files ncr53c8xx.c and ncr53c8xx.h check these defines with
#ifdef to enable script prefetching and disable 16-bit word transfers
respectively — both specific to the PA-RISC Zalon SCSI controller's
big-endian bus requirements.

These defines have been present since the initial git import in commit
1da177e4c3f4 ("Linux-2.6.12-rc2"). They predate the modern Kconfig
convention that CONFIG_ prefixed symbols should always originate from
Kconfig. The third define on the same line, SCSI_NCR_BIG_ENDIAN, already
correctly omits the CONFIG_ prefix.

The CONFIG_ prefix is misleading: these are not user-configurable
options and do not appear in any Kconfig menu. They are unconditionally
enabled for all Zalon builds. Remove the CONFIG_ prefix from both
symbols — renaming them to NCR53C8XX_PREFETCH and
SCSI_NCR53C8XX_NO_WORD_TRANSFERS — to match the convention used by
SCSI_NCR_BIG_ENDIAN on the same line and to avoid confusion with actual
Kconfig-managed symbols.

No functional change.

I submitted a patch to fix this reference earlier, but Hannes Reinecke suggested that removing the driver may be just as good here. The i2o driver layer was removed in 2015 with commit 4a72a7af462d ("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driver stayed around. The last non-cleanup patches I could find were from Miquel van Smoorenburg and Mark Salyzyn back in 2008, they might know if there is any chance of the hardware still being used anywhere.
