that leads to:

  CC      drivers/mtd/spi-nor/spi-nor.o
drivers/mtd/spi-nor/spi-nor.c: In function 'spi_nor_s3an_addr_convert':
drivers/mtd/spi-nor/spi-nor.c:359:11: warning: comparison of distinct
pointer types lacks a cast [enabled by default]


and if I do the casting

offset = do_div((uint64_t)addr, nor->page_size);

Unsinged long is more than enough for s3an. I think v7 is ok.
