In order to keep better track of when a feature got deprecated, and hence when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is introduced. These symbols are automatically selected when BR2_DEPRECATED is selected, and thus are transparent to the user. A deprecated feature will no longer depend on BR2_DEPRECATED directly, but rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does not yet exist, it has to be created in Config.in. When removing a deprecated feature, one should also check whether this was the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which case the latter can be removed from Config.in. A followup patch will make sure the overview is added to the list of deprecated features in the manual, so that a buildroot core developer can easily determine which features to remove in a given development cycle.

If your target CPU does not have a Floating Point Unit (FPU)

or a kernel FPU emulator, but you still wish to support
|

floating point functions, then everything will need to be

compiled with soft floating point support (-msoft-float).
