Subject: [PATCH 04/71] ncr5380: Remove more pointless macros
Date: Wed, 18 Nov 2015 19:34:59 +1100	[thread overview]
Message-ID: <20151118083456.362586813@telegraphics.com.au> (raw)
In-Reply-To: 20151118083455.331768508@telegraphics.com.au

[-- Attachment #1: ncr5380-remove-pointless-macros --]
[-- Type: text/plain, Size: 6150 bytes --]

ASM macro is never defined. rtrc in pas16.c is not used.
NCR5380_map_config, do_NCR5380_intr, do_t128_intr and do_pas16_intr
are unused. NCR_NOT_SET harms readability. Remove them.
