From: Raymond Mao <raymond.mao@riscstar.com>
This patch series introduces full support for the k1 SoC in SPL for
multiple boards.
The series enables the board by:
1. Adding the base board definition with device tree.
2. Bringing up essential clock sources and tree.
3. Initializing I2C buses for peripheral communication.
4. Integrating the PMIC driver for power management.
5. Adding regulator drivers for voltage domain control.
Change in v2:
- Use read_poll_timeout() in k1 i2c driver.
- Abandon to parse offset and size from Kconfig & Makefile for binman.
- Abandon to attach firmware image into the patch set.
- Update the related document and some minor changes.

* [PATCH] doc: spacemit: add K1 SPL build and test guide 2026-02-10 15:14 [PATCH v2 00/16] Add board support for Spacemit K1 SoC in SPL Raymond Mao ` (16 preceding siblings ...) 2026-02-25 14:53 ` [PATCH v2 00/16] Add board support for Spacemit K1 SoC in SPL Raymond Mao @ 2026-03-11 7:37 ` Guodong Xu 17 siblings, 0 replies; 24+ messages in thread From: Guodong Xu @ 2026-03-11 7:37 UTC (permalink / raw) To: u-boot Cc: trini, heinrich.schuchardt, rick, ycliang, raymond.mao, u-boot-spacemit, Guodong Xu The K1 SPL patchset requires DDR firmware integration and FSBL signing steps that are not covered by existing documentation. Add a SoC-level guide so reviewers and developers can build and test on hardware. Signed-off-by: Guodong Xu <guodong@riscstar.com> --- Following up on the discussion at yesterday's community meeting, this patch adds build and test instructions for the K1 SPL patchset [1]. This is placed as a SoC-level guide since the SPL build and flashing procedure is shared across all K1 boards. The existing bananapi-f3.rst will be updated to reference this in a future patch as more of the boot chain is upstreamed.
