I'm just trying to port the USB driver "musb" (for the AM335x platform) from linux kernel to barebox. But whenever I want to read any address in the range 0x47401400-0x474017ff, the barebox crashes with "unable to handle paging request". I have already tried to invoke a "map_io_sections(0x0, 0x47400000, 0x2000)", but it didn't help. Fortunately I can test it on the barebox command line with the command md -w 0x4740146c-0x4740146d In the linux kernel they are calling the "ioremap()" function for this memory range, but I didn't find an equivalent function in the barebox source. Do you have any idea, how to avoid the "paging request" failure here?
