2025-05-29dhelectronics: Include env.h to permit reading the environmentSimon Glass
This file reads from the environment but does not include the correct header. Update it. Signed-off-by: Simon Glass <sjg@chromium.org>
2024-12-07board: dhelectronics: Sync env variable dh_som_serial_number with SNChristoph Niedermaier
The env variable "SN" is used to store the serial number on DH electronics SoMs. New SoMs will use the variable "dh_som_serial_number". To ensure compatibility, these env variables are synchronized. This is achieved using callback functions. Signed-off-by: Christoph Niedermaier <cniedermaier@dh-electronics.com> Reviewed-by: Marek Vasut <marex@denx.de>
2024-12-07arm64: imx8mp: Read values from M24C32-D write-lockable page on DHCOM i.MX8MPChristoph Niedermaier
The new i.MX8M Plus DHCOM rev.200 is populated with M24C32-D EEPROM that contains an additional write-lockable page called ID page, which is populated with a structure containing ethernet MAC addresses, DH item number and DH serial number. Because the write-lockable page is not present on rev.100 i.MX8MP DHCOM SoM, test whether EEPROM ID page exists by setting up the i2c driver. There may be multiple EEPROMs with an ID page on this platform, always use the first one. The evaluation of the EEPROM ID page is done in two steps. First, the content is read and checked. This is done to cache the content of the EEPROM ID page. Second, the content is extracted from the EEPROM buffer by requesting it. For the ethernet MAC address the i.MX8M Plus DHCOM currently supports parsing address from multiple sources in the following priority order: 1) U-Boot environment 'ethaddr'/'eth1addr' environment variable 2) SoC OTP fuses 3) On-SoM EEPROM Add support for parsing the content of this new EEPROM ID page and place it between 2) and 3) on the priority list. The new entry is 2.5) On-SoM EEPROM write-lockable page. Signed-off-by: Christoph Niedermaier <cniedermaier@dh-electronics.com> Reviewed-by: Marek Vasut <marex@denx.de>
2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2024-04-05ARM: imx: stm32: Test whether ethernet node is enabled before reading MAC ↵Marek Vasut
EEPROM on DHSOM Check whether the ethernet interface is enabled at all before reading MAC EEPROM. As a cost saving measure, it can happen that the MAC EEPROM is not populated on SoMs which do not use ethernet.

2022-08-12board: dhelectronics: Implement common MAC address functionsPhilip Oberfichtner
This is a starting point for unifying duplicate code in the DH board files. The functions for setting up MAC addresses are very similar for the i.MX6, i.MX8 and stm32mp1 based boards. All pre-existing implementations follow the same logic: (1) Check if ethaddr is already set in the environment (2) If not, try to get it from a board specific location (e.g. fuse) (3) If not, try to get it from eeprom After this commit, (1) and (3) are implemented as common functions, ready to be used by board specific files. Furthermore there is an implementation of (2) for imx based boards. Signed-off-by: Philip Oberfichtner <pro@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
