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?
