Subject: [U-Boot] [PATCH v4 3/3] board: sama5d4_xplained: Set mac address from eeprom
Date: Fri, 1 Sep 2017 16:26:18 +0800 [thread overview]
Message-ID: <20170901082618.30622-4-wenyou.yang@microchip.com> (raw)
In-Reply-To: <20170901082618.30622-1-wenyou.yang@microchip.com>
Add the code to set the ethernet mac address from eeprom by using
the common code from the common folder.
Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com>
---
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.
