Re: [patch 15/16] powerpc: clean up usage of boot_dev

[s.hauer@pengutronix.de]

dev_t boot_dev is declared in arch/powerpc/kernel/setup_32.c
and in arch/powerpc/kernel/setup_64.c but not used in these files.
It is only used in arch/powerpc/platforms/powermac/setup.c, so make
it static in this file
