configs: k1: enable pinctrl and gpio

2026-07-21T09:42:44Z

Enable pinctrl and gpio configurations for Spacemit K1 SoC. Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu

spacemit: k1: Add multiple device tree support

2026-07-21T09:16:02Z

Enable multiple DTB support in the FIT image for the Spacemit K1 SoC, allowing a single U-Boot binary to support different board variants. The SPL reads the board type from EEPROM and selects the corresponding device tree at runtime via board_fit_config_name_match(), ensuring the correct hardware description is passed to U-Boot proper.

spl: k1: enable SPI NOR flash detection and boot

2026-07-21T09:16:01Z

Add nor_early_init() to probe the QSPI controller and SPI NOR flash in SPL. Switch spl_boot_device() to BOOT_DEVICE_SPI so the board boots from SPI flash. Change the default device tree to k1-musepi-pro, whose u-boot overlay already defines the QSPI controller and flash node with bootph-pre-ram markers. Enable the required SPI driver model and flash config options. Signed-off-by: Guodong Xu

board: k1: enable pmic in spl

2026-07-21T09:12:53Z

Add Spacemit P1 SoC support in SPL. And set the default voltage for BUCKs and LDOs. Also update MAINTAINERS: add Guodong Xu as co-maintainer, list the u-boot-spacemit mailing list, register the new K1 driver files (i2c, PMIC, regulator), and fix a pre-existing '@@' typo in Huan Zhou's email. Fixes: 1cd239f44438 ("riscv: spacemit: bananapi_f3: initial support added") Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu Tested-by: Songsong Zhang

spacemit: k1: Add DDR firmware support to SPL

2026-07-21T08:57:14Z

Include DDR initialization firmware in the SPL image. The firmware path can be specified via the DDR_FW_FILE environment variable. If the firmware is not found, an empty placeholder file is created to allow the build to proceed without DDR initialization support.

spacemit: k1: add TLV EEPROM support in SPL

2026-07-21T08:57:13Z

And support for required components including clock, I2C controller, and I2C EEPROM. Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu Tested-by: Songsong Zhang

board: k1: initialize clock and serial devices in SPL

2026-07-21T08:57:13Z

Initialize clock and serial devices in SPL. Otherwise, the device driver won't be loaded in SPL. Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu Tested-by: Songsong Zhang

spacemit: k1: enable SPL with debug UART

2026-07-21T08:57:13Z

Add SPL support featuring debug UART output for early boot diagnostics on K1 SoC. Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu Tested-by: Songsong Zhang

spacemit: k1: support multi-board infrastructure

2026-07-21T08:57:13Z

Restructure K1 SoC support to handle multiple boards through a single configuration: 1. Rename bananapi-f3_defconfig to spacemit_k1_defconfig. 2. Move all K1 board files to board/spacemit/k1/. 3. Replace TARGET_BANANAPI_F3 with TARGET_SPACEMIT_K1 and rename the board's .h header to k1.h. Eliminates the need for board-specific defconfigs while maintaining hardware compatibility.

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.
