From 714fd406daab6a98b2ee8d301c4888c113fdd818 Mon Sep 17 00:00:00 2001 From: Priyanka Jain Date: Thu, 30 Jan 2014 11:30:04 +0530 Subject: powerpc/t104xrdb: Add basic ethernet support This covers only non-L2 switch ethernet interfaces i.e. RGMII and SGMII interface for both T1040RDB and T1042RDB_PI T1040RDB is configured as serdes protocol 0x66 which can support following interfaces 2 RGMIIS on DTSEC4, DTSEC5 1 SGMII on DTSEC3 T1042RDB_PI is configured as serdes protocol 0x06 which can support following interfaces 2 RGMIIS on DTSEC4, DTSEC5 Signed-off-by: Poonam Aggrwal Signed-off-by: Priyanka Jain [York Sun: Minor change in commit message] Signed-off-by: York Sun --- board/freescale/t104xrdb/Makefile | 1 + board/freescale/t104xrdb/eth.c | 72 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 73 insertions(+) create mode 100644 board/freescale/t104xrdb/eth.c (limited to 'board') diff --git a/board/freescale/t104xrdb/Makefile b/board/freescale/t104xrdb/Makefile index 76c0c94b0e..e51fb7a7f4 100644 --- a/board/freescale/t104xrdb/Makefile +++ b/board/freescale/t104xrdb/Makefile @@ -7,6 +7,7 @@ obj-y += t104xrdb.o obj-y += ddr.o +obj-y += eth.o obj-$(CONFIG_PCI) += pci.o obj-y += law.o obj-y += tlb.o diff --git a/board/freescale/t104xrdb/eth.c b/board/freescale/t104xrdb/eth.c new file mode 100644 index 0000000000..0188fd4090 --- /dev/null +++ b/board/freescale/t104xrdb/eth.c @@ -0,0 +1,72 @@ +/* + * Copyright 2014 Freescale Semiconductor, Inc. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include +#include +#include +#include +#include +#include +#include + +#include "../common/fman.h" + +int board_eth_init(bd_t *bis) +{ +#ifdef CONFIG_FMAN_ENET + struct memac_mdio_info memac_mdio_info; + unsigned int i; + int phy_addr = 0; + printf("Initializing Fman\n"); + + memac_mdio_info.regs = + (struct memac_mdio_controller *)CONFIG_SYS_FM1_DTSEC_MDIO_ADDR; + memac_mdio_info.name = DEFAULT_FM_MDIO_NAME; + + /* Register the real 1G MDIO bus */ + fm_memac_mdio_init(bis, &memac_mdio_info); + + /* + * Program on board RGMII, SGMII PHY addresses. + */ + for (i = FM1_DTSEC1; i < FM1_DTSEC1 + CONFIG_SYS_NUM_FM1_DTSEC; i++) { + int idx = i - FM1_DTSEC1; + + switch (fm_info_get_enet_if(i)) { +#ifdef CONFIG_T1040RDB + case PHY_INTERFACE_MODE_SGMII: + /* T1040RDB only supports SGMII on DTSEC3 */ + fm_info_set_phy_address(FM1_DTSEC3, + CONFIG_SYS_SGMII1_PHY_ADDR); +#endif + case PHY_INTERFACE_MODE_RGMII: + if (FM1_DTSEC4 == i) + phy_addr = CONFIG_SYS_RGMII1_PHY_ADDR; + if (FM1_DTSEC5 == i) + phy_addr = CONFIG_SYS_RGMII2_PHY_ADDR; + fm_info_set_phy_address(i, phy_addr); + break; + case PHY_INTERFACE_MODE_QSGMII: + fm_info_set_phy_address(i, 0); + break; + case PHY_INTERFACE_MODE_NONE: + fm_info_set_phy_address(i, 0); + break; + default: + printf("Fman1: DTSEC%u set to unknown interface %i\n", + idx + 1, fm_info_get_enet_if(i)); + fm_info_set_phy_address(i, 0); + break; + } + fm_info_set_mdio(i, + miiphy_get_dev_by_name(DEFAULT_FM_MDIO_NAME)); + } + + cpu_eth_init(bis); +#endif + + return pci_eth_init(bis); +} -- cgit v1.2.1
