[patch 18/29] m68k/mac/: possible cleanups

From: Geert Uytterhoeven
Date: Thu Jul 17 2008 - 15:26:24 EST


From: Adrian Bunk <bunk@xxxxxxxxxx>

This patch contains the following possible cleanups:
- make the following needlessly global code (always) static:
- baboon.c: struct baboon
- baboon.c: baboon_irq()
- config.c: mac_orig_videoaddr
- config.c: mac_identify()
- config.c: mac_report_hardware()
- config.c: mac_debug_console_write()
- config.c: mac_sccb_console_write()
- config.c: mac_scca_console_write()
- config.c: mac_init_scc_port()
- oss.c: oss_irq()
- oss.c: oss_nubus_irq()
- psc.c: psc_debug_dump()
- psc.c: psc_dma_die_die_die()
- via.c: rbv_clear
- remove the unused bootparse.c
- #if 0 the following unused functions:
- config.c: mac_debugging_short()
- config.c: mac_debugging_long()
- remove the following unused code:
- config.c: mac_bisize
- config.c: mac_env
- config.c: mac_SCC_init_done
- config.c: mac_SCC_reset_done
- config.c: mac_init_scca_port()
- config.c: mac_init_sccb_port()
