[PATCH v3 00/16] Add board support for Spacemit K1 SoC in SPL

[Raymond Mao]

From: Raymond Mao <raymond.mao at riscstar.com>

This series adds SPL support for the SpacemiT K1 SoC, enabling boot
on K1-based boards such as the BananaPi F3.

To verify, please refer to the doc patch "doc: spacemit: add K1 SPL build
and test guide" [1], which is still valid and suggest to be included to
riscv/next.

Changes in v3:
- Merge CONFIG_ARCH_K1 and CONFIG_TARGET_BANANAPI_F3 into
  CONFIG_TARGET_SPACEMIT_K1. This configuration should be used for all
  boards with Spacemit K1 SoC.
- Remove CONFIG_SPL_RESET_SPACEMIT_K1, CONFIG_SPL_CLK_SPACEMIT_K1,
  CONFIG_SPL_PMIC_SPACEMIT_P1, CONFIG_SPL_DM_REGULATOR_SPACEMIT_P1.
  Since they're redundant for SPL stage.
- Fix the calculation on clock ID. While the clock driver is
  initialized in uboot stage, it'll be run twice. Without the
  protection, it'll cause panic in the second time.

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.
