Signed-off-by: Wenyou Yang Reviewed-by: Simon Glass --- Changes in v4: - Rebase the latest commit(8b3cec7da) on uboot/master. Changes in v3: - remove CONFIG_SPL_I2C_SUPPORT=y from the default configuration files. - rebase on [PATCH] misc: Makefile: Add condition on build i2c_eeprom. https://lists.denx.de/pipermail/u-boot/2017-August/300783.html Changes in v2: - Add a new patch to create board/$(VENDOR)/common folder to accommodate the common code and put the code to set the ethernet mac address from eeprom here. - Use the i2c_eeprom driver to read the mac address, instead of the dm i2c API directly. arch/arm/dts/at91-sama5d4_xplained.dts | 5 +++++ board/atmel/sama5d4_xplained/sama5d4_xplained.c | 12 ++++++++++++ configs/sama5d4_xplained_mmc_defconfig | 3 +++ configs/sama5d4_xplained_nandflash_defconfig | 3 +++ configs/sama5d4_xplained_spiflash_defconfig | 3 +++ include/configs/sama5d4_xplained.h | 2 ++ 6 files changed, 28 insertions(+) diff --git a/arch/arm/dts/at91-sama5d4_xplained.dts b/arch/arm/dts/at91-sama5d4_xplained.dts index ca6aff28e5..0592b31b91 100644 --- a/arch/arm/dts/at91-sama5d4_xplained.dts +++ b/arch/arm/dts/at91-sama5d4_xplained.dts @@ -88,6 +88,11 @@ i2c0: i2c@f8014000 { status = "okay"; + + i2c_eeprom: i2c_eeprom@5c { + compatible = "atmel,24mac402"; + reg = <0x5c>; + }; }; macb0: ethernet@f8020000 { diff --git a/board/atmel/sama5d4_xplained/sama5d4_xplained.c b/board/atmel/sama5d4_xplained/sama5d4_xplained.c index 854afcb622..248a31b8c4 100644 --- a/board/atmel/sama5d4_xplained/sama5d4_xplained.c +++ b/board/atmel/sama5d4_xplained/sama5d4_xplained.c @@ -192,6 +192,18 @@ int board_early_init_f(void) } #endif +#define AT24MAC_MAC_OFFSET 0x9a + +#ifdef CONFIG_MISC_INIT_R +int misc_init_r(void) +{ +#ifdef CONFIG_I2C_EEPROM + at91_set_ethaddr(AT24MAC_MAC_OFFSET); +#endif + return 0; +} +#endif + int board_init(void) { /* adress of boot parameters */ diff --git a/configs/sama5d4_xplained_mmc_defconfig b/configs/sama5d4_xplained_mmc_defconfig index de0ce40a56..792d011718 100644 --- a/configs/sama5d4_xplained_mmc_defconfig +++ b/configs/sama5d4_xplained_mmc_defconfig @@ -47,6 +47,9 @@ CONFIG_AT91_UTMI=y CONFIG_AT91_H32MX=y CONFIG_DM_GPIO=y CONFIG_AT91_GPIO=y +CONFIG_DM_I2C=y +CONFIG_SYS_I2C_AT91=y +CONFIG_I2C_EEPROM=y CONFIG_DM_MMC=y CONFIG_GENERIC_ATMEL_MCI=y CONFIG_DM_SPI_FLASH=y diff --git a/configs/sama5d4_xplained_nandflash_defconfig b/configs/sama5d4_xplained_nandflash_defconfig index cba3c8b640..3b0af5bf00 100644 --- a/configs/sama5d4_xplained_nandflash_defconfig +++ b/configs/sama5d4_xplained_nandflash_defconfig @@ -44,6 +44,9 @@ CONFIG_AT91_UTMI=y CONFIG_AT91_H32MX=y CONFIG_DM_GPIO=y CONFIG_AT91_GPIO=y +CONFIG_DM_I2C=y +CONFIG_SYS_I2C_AT91=y +CONFIG_I2C_EEPROM=y CONFIG_DM_MMC=y CONFIG_GENERIC_ATMEL_MCI=y CONFIG_DM_SPI_FLASH=y diff --git a/configs/sama5d4_xplained_spiflash_defconfig b/configs/sama5d4_xplained_spiflash_defconfig index 174e2bc5ba..26eb00598c 100644 --- a/configs/sama5d4_xplained_spiflash_defconfig +++ b/configs/sama5d4_xplained_spiflash_defconfig @@ -46,6 +46,9 @@ CONFIG_AT91_UTMI=y CONFIG_AT91_H32MX=y CONFIG_DM_GPIO=y CONFIG_AT91_GPIO=y +CONFIG_DM_I2C=y +CONFIG_SYS_I2C_AT91=y +CONFIG_I2C_EEPROM=y CONFIG_DM_MMC=y CONFIG_GENERIC_ATMEL_MCI=y CONFIG_DM_SPI_FLASH=y diff --git a/include/configs/sama5d4_xplained.h b/include/configs/sama5d4_xplained.h index c8462b0b64..08f865016d 100644 --- a/include/configs/sama5d4_xplained.h +++ b/include/configs/sama5d4_xplained.h @@ -12,6 +12,8 @@ #include "at91-sama5_common.h" +#define CONFIG_MISC_INIT_R + /* SDRAM */ #define CONFIG_NR_DRAM_BANKS 1 #define CONFIG_SYS_SDRAM_BASE ATMEL_BASE_DDRCS
