The host->page_size field should also -be removed and use always mtd->writesize instead. Follow up commits -will clean this up. - -Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> -Tested-by: Daniel Mack <zonque@gmail.com> -Signed-off-by: Brian Norris <computersforpeace@gmail.com> ---- - drivers/mtd/nand/pxa3xx_nand.c | 12 +++++++----- - 1 file changed, 7 insertions(+), 5 deletions(-) - ---- a/drivers/mtd/nand/pxa3xx_nand.c -+++ b/drivers/mtd/nand/pxa3xx_nand.c -@@ -201,8 +201,8 @@ struct pxa3xx_nand_info { - int use_spare; /* use spare ? */ - int is_ready; - -- unsigned int page_size; /* page size of attached chip */ -- unsigned int data_size; /* data size in FIFO */ -+ unsigned int fifo_size; /* max. data size in the FIFO */ -+ unsigned int data_size; /* data to be read from FIFO */ - unsigned int oob_size; - int retcode; - -@@ -307,16 +307,15 @@ static void pxa3xx_nand_set_timing(struc - - static void pxa3xx_set_datasize(struct pxa3xx_nand_info *info) - { -- struct pxa3xx_nand_host *host = info->host[info->cs]; - int oob_enable = info->reg_ndcr & NDCR_SPARE_EN; - -- info->data_size = host->page_size; -+ info->data_size = info->fifo_size; - if (!oob_enable) { - info->oob_size = 0; - return; - } - -- switch (host->page_size) { -+ switch (info->fifo_size) { - case 2048: - info->oob_size = (info->use_ecc) ? 40 : 64; - break; -@@ -933,9 +932,12 @@ static int pxa3xx_nand_detect_config(str - uint32_t ndcr = nand_readl(info, NDCR); - - if (ndcr & NDCR_PAGE_SZ) { -+ /* Controller's FIFO size */ -+ info->fifo_size = 2048; - host->page_size = 2048; - host->read_id_bytes = 4; - } else { -+ info->fifo_size = 512; - host->page_size = 512; - host->read_id_bytes = 2; - } |
