From 8ac0fba2da41620f4931a1007c71b0d4723eb02a Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Sun, 1 May 2016 17:50:29 -0400 Subject: [PATCH] isa: Decouple X86_32 dependency from the ISA Kconfig option The introduction of the ISA_BUS option blocks the compilation of ISA drivers on non-x86 platforms. The ISA_BUS configuration option should not be necessary if the X86_32 dependency can be decoupled from the ISA configuration option. This patch both removes the ISA_BUS configuration option entirely and removes the X86_32 dependency from the ISA configuration option.
