MIPS: BCM47XX Avoid compile error with MIPS allnoconfig
Currently MIPS allnoconfig with CONFIG_BCM47XX=y fails to compile due to
neither BCM47XX_BCMA nor BCM47XX_SSB being selected. This leads the
enumeration in arch/mips/include/asm/mach-bcm47xx/bcm47xx.h to be empty,
and compilation fails:
In file included from arch/mips/bcm47xx/irq.c:32:0:
./arch/mips/include/asm/mach-bcm47xx/bcm47xx.h:34:1: error: expected
identifier before '}' token
};
^
make[2]: *** [scripts/Makefile.build:314: arch/mips/bcm47xx/irq.o] Error 1
Fix this by ensuring that BCM47XX_SSB is selected if BCM47XX_BCMA is
not. This allows us to select either system or both, but not neither.
