-/* This function generates various test patterns useful for testing controller
- * and chip communication as well as chip behaviour.
- *
- * If a byte can be written multiple times, each time keeping 0-bits at 0
- * and changing 1-bits to 0 if the new value for that bit is 0, the effect
- * is essentially an AND operation. That's also the reason why this function
- * provides the result of AND between various patterns.
- *
- * Below is a list of patterns (and their block length).
- * Pattern 0 is 05 15 25 35 45 55 65 75 85 95 a5 b5 c5 d5 e5 f5 (16 Bytes)
- * Pattern 1 is 0a 1a 2a 3a 4a 5a 6a 7a 8a 9a aa ba ca da ea fa (16 Bytes)
- * Pattern 2 is 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f (16 Bytes)
- * Pattern 3 is a0 a1 a2 a3 a4 a5 a6 a7 a8 a9 aa ab ac ad ae af (16 Bytes)
- * Pattern 4 is 00 10 20 30 40 50 60 70 80 90 a0 b0 c0 d0 e0 f0 (16 Bytes)
- * Pattern 5 is 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f (16 Bytes)
- * Pattern 6 is 00 (1 Byte)
- * Pattern 7 is ff (1 Byte)
- * Patterns 0-7 have a big-endian block number in the last 2 bytes of each 256
- * byte block.
- *
- * Pattern 8 is 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 11... (256 B)
- * Pattern 9 is ff fe fd fc fb fa f9 f8 f7 f6 f5 f4 f3 f2 f1 f0 ef ee... (256 B)
- * Pattern 10 is 00 00 00 01 00 02 00 03 00 04... (128 kB big-endian counter)
- * Pattern 11 is ff ff ff fe ff fd ff fc ff fb... (128 kB big-endian downwards)
- * Pattern 12 is 00 (1 Byte)
- * Pattern 13 is ff (1 Byte)
- * Patterns 8-13 have no block number.
- *
- * Patterns 0-3 are created to detect and efficiently diagnose communication
- * slips like missed bits or bytes and their repetitive nature gives good visual
- * cues to the person inspecting the results. In addition, the following holds:
- * AND Pattern 0/1 == Pattern 4
- * AND Pattern 2/3 == Pattern 5
- * AND Pattern 0/1/2/3 == AND Pattern 4/5 == Pattern 6
- * A weakness of pattern 0-5 is the inability to detect swaps/copies between
- * any two 16-byte blocks except for the last 16-byte block in a 256-byte bloc.
- * They work perfectly for detecting any swaps/aliasing of blocks >= 256 bytes.
- * 0x5 and 0xa were picked because they are 0101 and 1010 binary.
- * Patterns 8-9 are best for detecting swaps/aliasing of blocks < 256 bytes.
- * Besides that, they provide for bit testing of the last two bytes of every
- * 256 byte block which contains the block number for patterns 0-6.
- * Patterns 10-11 are special purpose for detecting subblock aliasing with
- * block sizes >256 bytes (some Dataflash chips etc.)
- * AND Pattern 8/9 == Pattern 12
- * AND Pattern 10/11 == Pattern 12
- * Pattern 13 is the completely erased state.
- * None of the patterns can detect aliasing at boundaries which are a multiple
- * of 16 MBytes (but such chips do not exist anyway for Parallel/LPC/FWH/SPI).
