I'm missing documentation what these macros are supposed to be used
for?

Are they restricted to addresses in system RAM? Or intended to access
device registers? are they universal across all existing ARM systems,
i. e. are there not any configurations that might require any kind of
memory barriers or sync or considerations about caching?

Best regards,

Wolfgang Denk
