The ->read_xxx() methods are all passed the page number the NAND controller is supposed to read, but ->write_xxx() do not have such a parameter. This is a problem if we want to properly implement data scrambling/randomization in order to mitigate MLC sensibility to repeated pattern: to prevent bitflips in adjacent pages in the same block we need to avoid repeating the same pattern at the same offset in those pages, hence the randomizer/scrambler engine need to be passed the page value in order to adapt its seed accordingly. Moreover, adding the page parameter to the ->write_xxx() methods add some consistency to the current API.
