Hello,
i is the other way round.
as there is no translation on (real mode) when executing the irq routine, the data caching always is on.

The question is: Is it O.K., that the irq routines run in real mode, with all your I/O locations are cacheable, for example.
I expect to see problems when you enable data cache for I/O; there are many drivers in U-Boot which are not prepared for such conditions.
