board: dhelectronics: imx: Use second Ethernet MAC also from fuse

2026-04-21T23:49:39Z

Currently, the board specific code evaluates only the first Ethernet MAC address fuse, regardless of whether the first or second MAC address is requested. When the function to determine the second Ethernet MAC address is looking for the fused MAC address, it only reads the first MAC address fuse and increment it by one to set the second Ethernet MAC address. That is not the expected behavior when two MAC addresses are fused, because this causes the second fused MAC address to be ignored. Change this so that the second fused MAC address will be used.

arm64: imx8mp: Add 4G 1r DRAM timings on DH i.MX8MP DHCOM SoM

2026-04-02T12:11:52Z

Introduce timing patch which converts 2 GiB DRAM timings to 4 GiB 1-rank timings. This is a new configuration which carries IS43LQ32K01B DRAM part. The 512 MiB SoM strapping that was never used is repurposed for this part. Signed-off-by: Marek Vasut

arm64: imx8mp: Deduplicate 2G and 4G 2r DRAM timings on DH i.MX8MP DHCOM SoM

2026-04-02T12:11:51Z

The 2 GiB and 4 GiB 2-rank DRAM timings on i.MX8MP DHCOM are very similar. Instead of carrying around two copies of almost identical timing tables, implement a patch of the 2 GiB table to convert it into 4 GiB 2-rank table and pass the result to DRAM initialization code. This saves us 13640 Bytes in SPL, and frees up space for more DRAM initialization tables. Signed-off-by: Marek Vasut

arm64: imx8mp: Deduplicate DRAM size tables on DH i.MX8MP DHCOM SoM

2026-04-02T12:11:51Z

The DRAM size tables are shared by SPL and U-Boot proper, deduplicate those tables into lpddr4_timing.h . No functional change. Signed-off-by: Marek Vasut

arm64: imx8mp: Fold inline ECC into spl.c on DH i.MX8MP DHCOM SoM

2026-04-02T12:11:51Z

The inline ECC configuration is identical for 2 GiB DRAM variants and 4 GiB DRAM variants of the SoM, no matter the rank count. Fold the ECC configuration directly into spl.c to simplify the upcoming deduplication. No functional change. Signed-off-by: Marek Vasut

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22Z

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

board: dhelectronics: Move dh_add_item_number_and_serial_to_env() to common code

2025-11-17T16:45:11Z

Move dh_add_item_number_and_serial_to_env() to common code, so it can be used by both STM32MP13xx and iMX8MP DHSOM. No functional change. Signed-off-by: Marek Vasut Reviewed-by: Patrice Chotard

treewide: Remove empty board_init() function from all boards

2025-07-24T19:30:19Z

Commit 86acdce2ba88 ("common: add config for board_init() call") introduced CONFIG_BOARD_INIT option. This option can be disabled for the boards where board_init() function is not needed. Remove empty board_init() calls for all boards where it's possible, and disable CONFIG_BOARD_INIT in all related defconfigs. This cleanup was made semi-automatically using these scripts: [1]. No functional change, but the binary size for the modified boards is reduced a bit.

arm64: imx8mp: Gracefully handle disabled ENV_IS_IN_SPI_FLASH

2025-03-24T11:55:48Z

In case ENV_IS_IN_SPI_FLASH is disabled, returning ENVL_SPI_FLASH leads to failure to find environment driver on start up. Fix this by testing whether ENV_IS_IN_SPI_FLASH is enabled and if not, then return ENVL_NOWHERE instead. Signed-off-by: Marek Vasut

arm64: imx8mp: Read values from M24C32-D write-lockable page on DHCOM i.MX8MP

2024-12-07T12:07:44Z

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 Reviewed-by: Marek Vasut
