If memmap_phy is added, the flash A1 -addr space is [0, memmap_phy] which far more than flash size. -The AMBA memory will be divided into four parts and assign to -every chipselect. Every channel will has two valid chipselects. - -Signed-off-by: Yunhui Cui <yunhui.cui@nxp.com> ---- - drivers/mtd/spi-nor/fsl-quadspi.c | 14 ++++++++++---- - 1 file changed, 10 insertions(+), 4 deletions(-) - ---- a/drivers/mtd/spi-nor/fsl-quadspi.c -+++ b/drivers/mtd/spi-nor/fsl-quadspi.c -@@ -744,11 +744,17 @@ static void fsl_qspi_set_map_addr(struct - { - int nor_size = q->nor_size; - void __iomem *base = q->iobase; -+ u32 mem_base; - -- qspi_writel(q, nor_size + q->memmap_phy, base + QUADSPI_SFA1AD); -- qspi_writel(q, nor_size * 2 + q->memmap_phy, base + QUADSPI_SFA2AD); -- qspi_writel(q, nor_size * 3 + q->memmap_phy, base + QUADSPI_SFB1AD); -- qspi_writel(q, nor_size * 4 + q->memmap_phy, base + QUADSPI_SFB2AD); -+ if (has_added_amba_base_internal(q)) -+ mem_base = 0x0; -+ else -+ mem_base = q->memmap_phy; -+ -+ qspi_writel(q, nor_size + mem_base, base + QUADSPI_SFA1AD); -+ qspi_writel(q, nor_size * 2 + mem_base, base + QUADSPI_SFA2AD); -+ qspi_writel(q, nor_size * 3 + mem_base, base + QUADSPI_SFB1AD); -+ qspi_writel(q, nor_size * 4 + mem_base, base + QUADSPI_SFB2AD); - } - - /* |
