mips: BCM63XX: ensure that CPU_SUPPORTS_32BIT_KERNEL is set
Several header files need info on CONFIG_32BIT or CONFIG_64BIT,
but kconfig symbol BCM63XX does not provide that info. This leads
to many build errors, e.g.:
arch/mips/include/asm/page.h:196:13: error: use of undeclared identifier 'CAC_BASE'
return x - PAGE_OFFSET + PHYS_OFFSET;
arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET'
#define PAGE_OFFSET (CAC_BASE + PHYS_OFFSET)
arch/mips/include/asm/io.h:134:28: error: use of undeclared identifier 'CAC_BASE'
return (void *)(address + PAGE_OFFSET - PHYS_OFFSET);
arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET'
#define PAGE_OFFSET (CAC_BASE + PHYS_OFFSET)
arch/mips/include/asm/uaccess.h:82:10: error: use of undeclared identifier '__UA_LIMIT'
return (__UA_LIMIT & (addr | (addr + size) | __ua_size(size))) == 0;
Selecting the SYS_HAS_CPU_BMIPS* symbols causes SYS_HAS_CPU_BMIPS to be
set, which then selects CPU_SUPPORT_32BIT_KERNEL, which causes
CONFIG_32BIT to be set. (a bit more indirect than v1 [RFC].)
