[RFC,PATCH] Cleanup PC parallel port Kconfig
Ralf Baechle
ralf at linux-mips.org
Tue Jun 14 15:08:50 EDT 2011
The PC parallel port Kconfig as acquired one of those messy terms to
describe it's architecture dependencies:
depends on (!SPARC64 || PCI) && !SPARC32 && !M32R && !FRV && \
(!M68K || ISA) && !MN10300 && !AVR32 && !BLACKFIN
This isn't just ugly - it also almost certainly describes the dependencies
too coarse grainedly. This is an attempt at cleaing the mess up.
I tried to faithfully aproximate the old behaviour but the existing
behaviour seems inacurate if not wrong for some architectures or platforms.
To improve on this I rely on comments from other arch and platforms
maintainers. Any system that can take PCI multi-IO card or has a PC-style
parallel port on the mainboard should probably should now do a
select HAVE_PC_PARPORT. And some arch Kconfig files should further
restrict the use of HAVE_PC_PARPORT to only those platforms that actually
need it.
Thanks,
Ralf
