[En-Nut-Discussion] AVR: Equalizing names

[Uwe Bonnes]

Hello,

e.g. in nut/arch/avr/dev/ih_timer0_comp.c we have
#if defined(MCU_AT90CAN128) || defined(MCU_ATMEGA2560) || defined(MCU_ATMEGA2561)
#define INT_MASK_REG    TIMSK0
...
#else
#define INT_MASK_REG    TIMSK
...
#endif

Wouldn't a construct like

#if defined(TIMSK0)
#define INT_MASK_REG    TIMSK0
#else
#define INT_MASK_REG    TIMSK
#endif

make it easier to port to new devices? Otherwise the list of devices may
grow long with many devices supported.

Or maybe some AVR family related defined can be used like for above

#if defined(_AVR_IOCANXX_H_) || defined(_AVR_IOMXX0_1_H_)

Optinions?

Thanks
