Re: [PATCH] m68k/atari: EtherNEC - ethernet support (ne),>



Hi Geert,


Would you be OK if I expanded the comment like this?

/* ne.c is used on m68k Atari and Q40 computers - the Atari ROM-port
adapter is 8-bit, Q40 uses ISA */

DaveM already applied it to his tree, and sent a pull request to Linus.

OK - won't resend then unless explicitly requested.

Many thanks, Dave!

This would limit the runtime test to the case where it is actually
needed (untested):

#elif defined(CONFIG_ATARI) && defined(CONFIG_Q40)
/* multiplatform m68k kernel - the Atari ROM-port adapter is 8-bit,
Q40 uses ISA */
#  define DCR_VAL (MACH_IS_ATARI ? 0x48 : 0x49)
#elif defined(CONFIG_ATARI) /* no Q40 support - 8-bit mode on Atari ROM port */
#  define DCR_VAL 0x48
#else
#  define DCR_VAL 0x49
#endif

MACH_IS_ATARI already evaluates to a constant on single-platform
kernels, so this is optimized at compile time.
Hence there's not really a need for this.

I was hoping it would. More of an attempt to make the logic easier to understand, but a comment would be sufficient (and avoid redundancy).

Are there any other m68k platforms that use the ne.c driver, Geert?
apne, hydra and zorro8390 all have their own separate drivers - any
others?

Not that I'm aware of. Only Q40 has CONFIG_NE2000 in defconfig.

Good - we can finally put this one to rest.

Cheers,

   Michael
