In create_vector_table() failure of request_sdram_region() is expected and not an error, so putting an error message into request_sdram_region() is not a good idea. What we could do though is to print an error message based on a "verbose" input flag. > > The commid introduce necessary chages but I have no idea > how to change this part of arch/arm/cpu/mmu.c: > > if (!request_sdram_region("ttb", (unsigned long)ttb, SZ_16K)) > /* > * This can mean that: > * - the early MMU code has put the ttb into a place > * which we don't have inside our available memory > * - Somebody else has occupied the ttb region which means > * the ttb will get corrupted. > */ > pr_crit("Critical Error: Can't request SDRAM region for ttb at %p\n", > ttb); I think the message should stay like it is.
