| 975 | * AND Pattern 0/1 == Pattern 4 |
| 976 | * AND Pattern 2/3 == Pattern 5 |
| 977 | * AND Pattern 0/1/2/3 == AND Pattern 4/5 == Pattern 6 |
| 978 | * A weakness of pattern 0-5 is the inability to detect swaps/copies between |
| 979 | * any two 16-byte blocks except for the last 16-byte block in a 256-byte bloc. |
| 980 | * They work perfectly for detecting any swaps/aliasing of blocks >= 256 bytes. |
| 981 | * 0x5 and 0xa were picked because they are 0101 and 1010 binary. |
| 982 | * Patterns 8-9 are best for detecting swaps/aliasing of blocks < 256 bytes. |
| 983 | * Besides that, they provide for bit testing of the last two bytes of every |
| 984 | * 256 byte block which contains the block number for patterns 0-6. |
| 985 | * Patterns 10-11 are special purpose for detecting subblock aliasing with |
| 986 | * block sizes >256 bytes (some Dataflash chips etc.) |
| 987 | * AND Pattern 8/9 == Pattern 12 |
| 988 | * AND Pattern 10/11 == Pattern 12 |
| 989 | * Pattern 13 is the completely erased state. |
| 990 | * None of the patterns can detect aliasing at boundaries which are a multiple |
| 991 | * of 16 MBytes (but such chips do not exist anyway for Parallel/LPC/FWH/SPI). |
