Signature bytes wrong for a number of devices

[stefanrueger]

Some SIGNATURE_2 values are wrong in io header files.

iom164.h should be:

#if defined(__AVR_ATmega164A__)
#define SIGNATURE_2 0x0F
#else
#define SIGNATURE_2 0x0A
#endif

iom324.h should be

#if defined(__AVR_ATmega324A__)
#define SIGNATURE_2 0x15
#else
#define SIGNATURE_2 0x08
#endif

see datasheet page 298

---

iom169.h should be

#if defined(__AVR_ATmega169A__)
#define SIGNATURE_2 0x11
#else
#define SIGNATURE_2 0x05
#endif

iom329.h should be

#if defined (__AVR_ATmega329P__) || defined (__AVR_ATmega329PA__)   
#define SIGNATURE_2 0x0B
#else
#define SIGNATURE_2 0x03
#endif

iom3290.h should be

#if defined (__AVR_ATmega3290P__)
#define SIGNATURE_2 0x0C
#else
#define SIGNATURE_2 0x04
#endif

iom6490.h should be

#if defined (__AVR_ATmega6490P__)
#define SIGNATURE_2 0x0C
#else
#define SIGNATURE_2 0x04
#endif

see datasheet 169/329/p/pa, page 294
and datasheet 329p page 299

iom325.h should be

#if defined (__AVR_ATmega325P__)
#define SIGNATURE_2 0x0D
#else
#define SIGNATURE_2 0x05
#endif

iom645.h should be

#if defined (__AVR_ATmega645P__)
#define SIGNATURE_2 0x0D
#else
#define SIGNATURE_2 0x05
#endif

iom3250.h should be

#if defined (__AVR_ATmega3250P__)
#define SIGNATURE_2 0x0E
#else
#define SIGNATURE_2 0x06
#endif

iom6450.h should be

#if defined (__AVR_ATmega6450P__)
#define SIGNATURE_2 0x0E
#else
#define SIGNATURE_2 0x06
#endif

see datasheet 165/325/p/pa, page 264
and datasheet 325p page 274

#if defined (__AVR_ATmega325P__)

This lacks the ATmega325PA which also needs 0x0D (see ATDF file).

More wrong signature bytes:

iotn4.h and iotn5.h should define SIGNATURE_1 to 0x8F (not 0x90). See .atdf files and avrdude signature entries.

---

io4434.h should define SIGNATURE_1 to 0x92 (not 0x93). See avrdude signature entries (consistent with 0x92 typically implying 4 kB flash).

It also should define SIGNATURE_2 to 0x02 (not 0x03). See avrdude signature entries. The signatures that are currently defined for the AT90S4434 are actually those from the AT90S8535.

---

Following the change of signature in avrdude for the ATmega165, the file iom165.h should now define SIGNATURE_2 as 0x10. See avrdude issue 899 and commit.
