[PATCH v6 0/2] riscv: spacemit: add support for bananapi-f3

[Huan Zhou]

Banana Pi F3 board is a industrial grade RISC-V development board, it
design with SpacemiT K1 8 core RISC-V chip, CPU integrates 2.0 TOPs AI
computing power. 4G DDR and 16G eMMC onboard. 2x GbE Ethernet port, 4x USB
3.0 and PCIe for M.2 interface, support HDMI and Dual MIPI-CSI Camera.

This patch introduces fundamental support for the Banana Pi F3 board,
encompassing UART, CPU, and PLIC support. This ensures that U-Boot can
operate in serial console mode.

Changes in v6:
- Rebase the patch to the latest branch.
- Add small comment in bananapi-f3.h
- Add tag in previous patch(e.g reviewed by or tested by)
- Add fastboot burn procedure in doc.
- Link to v5: https://lore.kernel.org/r/20241209-pickup-bpif3-v5-0-92f801b7c6c1@gmail.com

Changes in v5:
- Formal the name from Bananapif3 -> Banana Pi BPI-F3
- Trailing whitespace
- New blank line at EOF in spacemit/index.rst
- Link to v4: https://lore.kernel.org/r/20241129-pickup-bpif3-v4-0-e99fabf66e33@gmail.com

Changes in v4:
- Change uart compatible in k1.dtsi in v3, cause related driver in not implemented in u-boot.
- Update doc, show how to validate the patch.
- Update maintainer, remove kongyang cause he lefted.
- Link to v3: https://lore.kernel.org/r/20241114-pickup-bpif3-v3-0-98a45802ab79@gmail.com

Changes in v3:
- Add base commit
- Clear redifinition warning while building in UART_IIR_ID
- Change underscore to dash in bananapi*f3
- Update maintainer
- link to v2 https://lore.kernel.org/u-boot/20240718043329.1500-1-seashell11234455@gmail.com/

Changes in v2:
- Change license to GPL-2.0-or-later
- Add memory node for dts
- Add ft_board_setup function for kernel memory init
- Use default prompt
- links to v1 https://lore.kernel.org/u-boot/20240714150828.736-1-seashell11234455@gmail.com/
