quite possibly a silly question but i'm looking at the header files related to the powerpc local bus local access windows (of which i am still woefully ignorant), and i see the following in two different header files under arch/powerpc/include/asm.

fsl_law.h:

#define LAW_EN 0x80000000

#define SET_LAW_ENTRY(idx, a, sz, trgt) \ { .index = idx, .addr = a, .size = sz, .trgt_id = trgt }

#define SET_LAW(a, sz, trgt) \ { .index = -1, .addr = a, .size = sz, .trgt_id = trgt }

enum law_size { LAW_SIZE_4K = 0xb, LAW_SIZE_8K, LAW_SIZE_16K, LAW_SIZE_32K, LAW_SIZE_64K, LAW_SIZE_128K, LAW_SIZE_256K, LAW_SIZE_512K, LAW_SIZE_1M, LAW_SIZE_2M, LAW_SIZE_4M, LAW_SIZE_8M, LAW_SIZE_16M, LAW_SIZE_32M, LAW_SIZE_64M, LAW_SIZE_128M, LAW_SIZE_256M, LAW_SIZE_512M, LAW_SIZE_1G, LAW_SIZE_2G, LAW_SIZE_4G, LAW_SIZE_8G, LAW_SIZE_16G, LAW_SIZE_32G, };

fsl_lbc.h

#define LBLAWAR_EN 0x80000000 #define LBLAWAR_4KB 0x0000000B #define LBLAWAR_8KB 0x0000000C #define LBLAWAR_16KB 0x0000000D #define LBLAWAR_32KB 0x0000000E #define LBLAWAR_64KB 0x0000000F #define LBLAWAR_128KB 0x00000010 #define LBLAWAR_256KB 0x00000011 #define LBLAWAR_512KB 0x00000012 #define LBLAWAR_1MB 0x00000013 #define LBLAWAR_2MB 0x00000014 #define LBLAWAR_4MB 0x00000015 #define LBLAWAR_8MB 0x00000016 #define LBLAWAR_16MB 0x00000017 #define LBLAWAR_32MB 0x00000018 #define LBLAWAR_64MB 0x00000019 #define LBLAWAR_128MB 0x0000001A #define LBLAWAR_256MB 0x0000001B #define LBLAWAR_512MB 0x0000001C #define LBLAWAR_1GB 0x0000001D #define LBLAWAR_2GB 0x0000001E

that kind of looks like the same information, just with different macro names. is there really a different meaning for that content between those two files?
