The default configuration for QSPI AHB bus can't support 16MB+. But some flash on NXP layerscape board are more than 16MB.

Signed-off-by: Yuan Yao yao.yuan@nxp.com --- Changed in v3: Rename the CONFIG_SYS_QSPI_ADDR to SYS_FSL_QSPI_ADDR. Changed in v2: Remove the CONFIG_QSPI_AHB_INIT into Kconfig. --- arch/arm/cpu/armv8/fsl-layerscape/Kconfig | 7 ++++ arch/arm/cpu/armv8/fsl-layerscape/soc.c | 42 ++++++++++++++++++++++ .../include/asm/arch-fsl-layerscape/immap_lsch2.h | 1 + .../include/asm/arch-fsl-layerscape/immap_lsch3.h | 1 + configs/ls1012afrdm_qspi_defconfig | 1 + configs/ls1012aqds_qspi_defconfig | 1 + configs/ls1012ardb_qspi_defconfig | 1 + configs/ls1046ardb_qspi_defconfig | 1 + 9 files changed, 56 insertions(+)
