Latest master sources have a regression due migrate to use platform_device_register functions. Now I cannot register cfi_flash device which resides at 0x0, because it have conflicts with "mem" command which have same start address. Thanks! --- _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 2+ messages in thread

Or we can provide virtual bus ("system" for example) for /dev/mem device. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 2+ messages in thread
