Some SPI controllers can't write nor->page_size bytes in a single step because their TX FIFO is too small, but when that happens we should make sure a WRITE_EN command before each write access and READ_SR command after each write access is issued. We should allow nor->write() to return a size that is smaller than the requested write size to gracefully handle this case. Also, the spi_nor_write_data() should return the actual number of bytes that were written during the spi_mem_exec_op() operation. This patch is a combination of two commits backported from kernel: commit 630d6bd8a3b4 ("mtd: spi-nor: Support controllers with limit ...") commit 3baa8ec88c2f ("mtd: devices: m25p80: Make sure WRITE_EN is ...")
