There is one standard + SPI flash driver which knows how to probe most chips + supported by U-Boot. The uclass interface is defined in + include/spi_flash.h, but is currently fully compatible + with the old interface to avoid confusion and duplication + during the transition parent. SPI and SPI flash must be + enabled together (it is not possible to use driver model + for one and not the other). diff --git a/drivers/net/Makefile b/drivers/net/Makefile index 46c4ac6..b8b0803 100644 --- a/drivers/net/Makefile +++ b/drivers/net/Makefile @@ -33,7 +33,6 @@ obj-$(CONFIG_FTMAC110) += ftmac110.o obj-$(CONFIG_FTMAC100) += ftmac100.o obj-$(CONFIG_GRETH) += greth.o obj-$(CONFIG_DRIVER_TI_KEYSTONE_NET) += keystone_net.o -obj-$(CONFIG_DRIVER_KS8695ETH) += ks8695eth.o obj-$(CONFIG_KS8851_MLL) += ks8851_mll.o obj-$(CONFIG_LAN91C96) += lan91c96.o obj-$(CONFIG_MACB) += macb.o @@ -65,5 +64,5 @@ obj-$(CONFIG_XILINX_EMACLITE) += xilinx_emaclite.o obj-$(CONFIG_XILINX_LL_TEMAC) += xilinx_ll_temac.o xilinx_ll_temac_mdio.o \ xilinx_ll_temac_fifo.o xilinx_ll_temac_sdma.o obj-$(CONFIG_ZYNQ_GEM) += zynq_gem.o -obj-$(CONFIG_FSL_MC_ENET) += fsl_mc/ +obj-$(CONFIG_FSL_MC_ENET) += fsl-mc/ obj-$(CONFIG_VSC9953) += vsc9953.o diff --git a/drivers/net/fsl_mc/Makefile b/drivers/net/fsl-mc/Makefile index 4834086..206ac6b 100644 --- a/drivers/net/fsl_mc/Makefile +++ b/drivers/net/fsl-mc/Makefile @@ -5,4 +5,6 @@ # # Layerscape MC driver -obj-y += mc.o +obj-y += mc.o \ + mc_sys.o \ + dpmng.o diff --git a/drivers/net/fsl-mc/dpmng.c b/drivers/net/fsl-mc/dpmng.c new file mode 100644 index 0000000..cc14c7b --- /dev/null +++ b/drivers/net/fsl-mc/dpmng.c @@ -0,0 +1,91 @@ +/* Copyright 2014 Freescale Semiconductor Inc. + * + * SPDX-License-Identifier: GPL-2.0+ + */ +#include <fsl-mc/fsl_mc_sys.h> +#include <fsl-mc/fsl_mc_cmd.h> +#include <fsl-mc/fsl_dpmng.h> +#include "fsl_dpmng_cmd.h" + +int mc_get_version(struct fsl_mc_io *mc_io, struct mc_version *mc_ver_info) +{ + struct mc_command cmd = { 0 };
