From 606576d54b673119d956cf4b9b24b098c1c05196 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 29 Jan 2016 09:14:54 +0100 Subject: arm: mvebu: Add basic support for Armada 375 eval board db-88f6720 This patch adds basic support for the Marvell A375 eval board. Tested are the following interfaces: - I2C - SPI - SPI NOR - Ethernet (mvpp2), port 0 & 1 Currently the A375 SerDes and DDR3 init code is not intergrated. So the SPL U-Boot is not fully functional. Right now, this A375 mainline U-Boot can only be used by chainloading it via the original Marvell U-Boot. This can be done via this command: => tftpboot 00800000 a375/u-boot-dtb.bin;go 00800000 Signed-off-by: Stefan Roese Cc: Luka Perkov --- board/Marvell/db-88f6720/MAINTAINERS | 6 +++ board/Marvell/db-88f6720/Makefile | 7 +++ board/Marvell/db-88f6720/db-88f6720.c | 91 +++++++++++++++++++++++++++++++++++ board/Marvell/db-88f6720/kwbimage.cfg | 12 +++++ 4 files changed, 116 insertions(+) create mode 100644 board/Marvell/db-88f6720/MAINTAINERS create mode 100644 board/Marvell/db-88f6720/Makefile create mode 100644 board/Marvell/db-88f6720/db-88f6720.c create mode 100644 board/Marvell/db-88f6720/kwbimage.cfg (limited to 'board/Marvell') diff --git a/board/Marvell/db-88f6720/MAINTAINERS b/board/Marvell/db-88f6720/MAINTAINERS new file mode 100644 index 0000000..a27d1c2 --- /dev/null +++ b/board/Marvell/db-88f6720/MAINTAINERS @@ -0,0 +1,6 @@ +DB_88F6720 BOARD +M: Stefan Roese +S: Maintained +F: board/Marvell/db-88f6720/ +F: include/configs/db-88f6720.h +F: configs/db-88f6720_defconfig diff --git a/board/Marvell/db-88f6720/Makefile b/board/Marvell/db-88f6720/Makefile new file mode 100644 index 0000000..7a5b512 --- /dev/null +++ b/board/Marvell/db-88f6720/Makefile @@ -0,0 +1,7 @@ +# +# Copyright (C) 2016 Stefan Roese +# +# SPDX-License-Identifier: GPL-2.0+ +# + +obj-y := db-88f6720.o diff --git a/board/Marvell/db-88f6720/db-88f6720.c b/board/Marvell/db-88f6720/db-88f6720.c new file mode 100644 index 0000000..b6e00f3 --- /dev/null +++ b/board/Marvell/db-88f6720/db-88f6720.c @@ -0,0 +1,91 @@ +/* + * Copyright (C) 2016 Stefan Roese + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include +#include +#include +#include +#include +#include + +DECLARE_GLOBAL_DATA_PTR; + +/* + * Those values and defines are taken from the Marvell U-Boot version + * "u-boot-2013.01-2014_T2.0" for the board Armada 375 DB-88F6720 + */ +#define DB_88F6720_MPP0_7 0x00020020 /* SPI */ +#define DB_88F6720_MPP8_15 0x22000022 /* SPI , I2C */ +#define DB_88F6720_MPP16_23 0x22222222 /* UART, TDM*/ +#define DB_88F6720_MPP24_31 0x33333333 /* SDIO, SPI1*/ +#define DB_88F6720_MPP32_39 0x04403330 /* SPI1, External SMI */ +#define DB_88F6720_MPP40_47 0x22002044 /* UART1, GE0, SATA0 LED */ +#define DB_88F6720_MPP48_55 0x22222222 /* GE0 */ +#define DB_88F6720_MPP56_63 0x04444422 /* GE0 , LED_MATRIX, GPIO */ +#define DB_88F6720_MPP64_67 0x014 /* LED_MATRIX, SATA1 LED*/ + +#define DB_88F6720_GPP_OUT_ENA_LOW 0xFFFFFFFF +#define DB_88F6720_GPP_OUT_ENA_MID 0x7FFFFFFF +#define DB_88F6720_GPP_OUT_ENA_HIGH 0xFFFFFFFF +#define DB_88F6720_GPP_OUT_VAL_LOW 0x0 +#define DB_88F6720_GPP_OUT_VAL_MID BIT(31) /* SATA Power output enable */ +#define DB_88F6720_GPP_OUT_VAL_HIGH 0x0 +#define DB_88F6720_GPP_POL_LOW 0x0 +#define DB_88F6720_GPP_POL_MID 0x0 +#define DB_88F6720_GPP_POL_HIGH 0x0 + +int board_early_init_f(void) +{ + /* Configure MPP */ + writel(DB_88F6720_MPP0_7, MVEBU_MPP_BASE + 0x00); + writel(DB_88F6720_MPP8_15, MVEBU_MPP_BASE + 0x04); + writel(DB_88F6720_MPP16_23, MVEBU_MPP_BASE + 0x08); + writel(DB_88F6720_MPP24_31, MVEBU_MPP_BASE + 0x0c); + writel(DB_88F6720_MPP32_39, MVEBU_MPP_BASE + 0x10); + writel(DB_88F6720_MPP40_47, MVEBU_MPP_BASE + 0x14); + writel(DB_88F6720_MPP48_55, MVEBU_MPP_BASE + 0x18); + writel(DB_88F6720_MPP56_63, MVEBU_MPP_BASE + 0x1c); + writel(DB_88F6720_MPP64_67, MVEBU_MPP_BASE + 0x20); + + /* Configure GPIO */ + /* Set GPP Out value */ + writel(DB_88F6720_GPP_OUT_VAL_LOW, MVEBU_GPIO0_BASE + 0x00); + writel(DB_88F6720_GPP_OUT_VAL_MID, MVEBU_GPIO1_BASE + 0x00); + writel(DB_88F6720_GPP_OUT_VAL_HIGH, MVEBU_GPIO2_BASE + 0x00); + + /* Set GPP Polarity */ + writel(DB_88F6720_GPP_POL_LOW, MVEBU_GPIO0_BASE + 0x0c); + writel(DB_88F6720_GPP_POL_MID, MVEBU_GPIO1_BASE + 0x0c); + writel(DB_88F6720_GPP_POL_HIGH, MVEBU_GPIO2_BASE + 0x0c); + + /* Set GPP Out Enable */ + writel(DB_88F6720_GPP_OUT_ENA_LOW, MVEBU_GPIO0_BASE + 0x04); + writel(DB_88F6720_GPP_OUT_ENA_MID, MVEBU_GPIO1_BASE + 0x04); + writel(DB_88F6720_GPP_OUT_ENA_HIGH, MVEBU_GPIO2_BASE + 0x04); + + return 0; +} + +int board_init(void) +{ + /* adress of boot parameters */ + gd->bd->bi_boot_params = mvebu_sdram_bar(0) + 0x100; + + return 0; +} + +int checkboard(void) +{ + puts("Board: Marvell DB-88F6720\n"); + + return 0; +} + +int board_eth_init(bd_t *bis) +{ + cpu_eth_init(bis); /* Built in controller(s) come first */ + return pci_eth_init(bis); +} diff --git a/board/Marvell/db-88f6720/kwbimage.cfg b/board/Marvell/db-88f6720/kwbimage.cfg new file mode 100644 index 0000000..1f748db --- /dev/null +++ b/board/Marvell/db-88f6720/kwbimage.cfg @@ -0,0 +1,12 @@ +# +# Copyright (C) 2014 Stefan Roese +# + +# Armada XP uses version 1 image format +VERSION 1 + +# Boot Media configurations +BOOT_FROM spi + +# Binary Header (bin_hdr) with DDR3 training code +BINARY spl/u-boot-spl-dtb.bin 0000005b 00000068 -- cgit v1.1
