Dear Reinhard Arlt,
In message 4C2AEC16.9080906@t-online.de you wrote:
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.
Best regards,
Wolfgang Denk
