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;
