The _WRAP thing is needed to make sure there is a user-visible boolean
option in the legacy menu, and to make sure you only select BR2_LEGACY
when the old option is not empty.
However, come to think of it, wouldn't it be enough to keep it as a
string option and add
select BR2_LEGACY if BR2_LINUX_KERNEL_CUSTOM_GIT_REPO_URL != ""
? Although I guess Thomas has tested this already.
Looking again at the patch, though, I wonder if it works at all. Aren't
the old options that have no symbol definition removed? I think there
should still be a
config BR2_LINUX_KERNEL_CUSTOM_GIT_REPO_URL
string
in Config.in.legacy.
But then, it will not be possible to modify the string anymore... so
there is no escape...
Argh, Kconfig...
Regards,
Arnout
