FPGA and NAND access are valid use-case during QSPI boot So why IFC controller is being disabled from device tree. > Signed-off-by: Gong Qianyu <qianyu.g...@nxp.com> > > diff --git a/arch/arm/cpu/armv8/fsl-layerscape/fdt.c > b/arch/arm/cpu/armv8/fsl-layerscape/fdt.c > index 4e4861d..5bb3048 100644 > --- a/arch/arm/cpu/armv8/fsl-layerscape/fdt.c > +++ b/arch/arm/cpu/armv8/fsl-layerscape/fdt.c > @@ -204,4 +204,11 @@ void ft_cpu_setup(void *blob, bd_t *bd) #ifdef > CONFIG_FSL_LSCH3 > fdt_fixup_smmu(blob); > #endif > + > +#ifdef CONFIG_LS1043A I will suggest to avoid SoC specific defines --prabhakar _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
