Hi,

Adding Santosh to Cc on this one.

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.

Yes there is no clean way currently to enable this errata for
multiplatform.
 

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.

From what I remember the plan was to try to come up with a

multiplatform friendly way of doing this errata. Santosh,
any suggestions here? Should we just remove the code as it
seems nobody has complained about it for a few years now?

Regards,

Tony
