Browse Source 
iomem pointers should be casted to unsigned long to avoid
-Wpointer-to-int-cast warnings when compiling on 64-bit platform (e.g.
with COMPILE_TEST):

    drivers/mtd/nand/onenand/samsung_mtd.c: In function ‘s3c_onenand_readw’:
    drivers/mtd/nand/onenand/samsung_mtd.c:251:6: warning:
        cast from pointer to integer of different size [-Wpointer-to-int-cast]
      if ((unsigned int) addr < ONENAND_DATARAM && onenand->bootram_command) {
