Subject: Dead Kconfig Option OMAP4_ERRATA_I688
During the research for my masters thesis i came across the
OMAP4_ERRATA_I688 option and realized, it is never possible to enable
this option.
The a62a6e98 commit added the "&& !ARCH_MULTIPLATFORM" dependency to
disable this option for multiplatforms. However, because of enclosing
dependencies, this option isn't available for non-MULTIPLATFORM
configurations either.
CONFIG_OMAP4_ERRATA_I688 is defined in the menu "TI OMAP/AM/DM/DRA
Family" which depends on ARCH_MULTI_V6 || ARCH_MULTI_V7. (in
arch/arm/mach-omap2/Kconfig)
ARCH_MULTI_V6 and ARCH_MULTI_V7 however are defined in the menu
"Multiple platform selection" which depends on ARCH_MULTIPLATFORM (in
arch/arm/Kconfig)
Which is a contradiction.
There are no selects on OMAP4_ERRATA_I688, which would ignore
dependencies, either.
The question is:
Was disabling this option for non-MULTIPLATFORM configurations also intentional?
i have added a minimal example of the problem.
