Subject: powerpc: Fix build error with CONFIG_PCI=n
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3484a31fce22348b9034024cf9368ab2dbbfd0ab;p=openwrt%2Fstaging%2Fblogic.git

powerpc: Fix build error with CONFIG_PCI=n

Fix ppc 32 build failure as reported here:

http://kisskb.ellerman.id.au/kisskb/buildresult/11663513/

The error is as follows:

arch/powerpc/include/asm/floppy.h:142:20: error: 'isa_bridge_pcidev' undeclared
(first use in this function)

This is happening since floppy.o is enabled by BLK_DEV_FD which depends on
ARCH_MAY_HAVE_PC_FDC which is in-turn enabled if PPC_PSERIES=n.

The following commit changes the dependency so that ARCH_MAY_HAVE_PC_FDC is
dependent exclusively on PCI since otherwise it will not compile.
