This is name space pollution t best, and has potential to cause
unwanted side effects.  This needs thorough checking and cleanup, if
it should turn out thatthese macros are used only to select specific
bootcount implementations - in that case, they should be renamed into
something like CONFIG_BOOTCOUNT_* or such.

Heiko, maybe you could have a look tat that, please?

Best regards,
