quartz64a: add vendor kernel support

[rpardini]

• yes, board is "fully mainline" for years now, but still one wants
  • rkmpp
  • rknpu
• change family to rk35xx, but:
  • keep mainline u-boot for now
• kernel DT adapted from https://gitlab.com/pine64-org/quartz-bsp/rockchip-linux/-/blob/quartz64/arch/arm64/boot/dts/rockchip/rk3566-quartz64.dts?ref_type=heads
  • applied amazingfate's advice from 2023 ref panfrost and vp0
    • see update rk35xx legacy kernel to 5.10 #4794 (comment)

Walkthrough

This change updates two configuration parameters in the Quartz64a board configuration file. The BOARDFAMILY identifier is changed from "rockchip64" to "rk35xx", and the KERNEL_TARGET is extended from "current,edge" to "current,edge,vendor" to include vendor kernel support.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

This is a straightforward, minimal configuration change affecting a single file with two simple value assignments. No complex logic or structural modifications are present.

Pre-merge checks and finishing touches

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The pull request title "quartz64a: add vendor kernel support" directly reflects the main objective of the changes in the file config/boards/quartz64a.csc. The changes update KERNEL_TARGET to include "vendor" and modify BOARDFAMILY to "rk35xx" to enable vendor kernel support for additional libraries like rkmpp and rknpu. The title is concise, specific to the primary change, and clearly communicates the intent of the pull request.
Description Check	✅ Passed	The pull request description is directly related to the changeset and provides meaningful context for the modifications. It explains that vendor kernel support is needed for rkmpp and rknpu despite the board being mainline-based, justifies the boardfamily change to rk35xx while preserving mainline U-Boot, and references the kernel device tree source and specific technical advice applied. The description clearly articulates the rationale and implementation details of the changes being made.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.

Learning: In the Armbian build system, vendor branch configurations in family files are designed to be shared across multiple SoCs within the same family that use the same vendor kernel tree. For example, rk35xx and rockchip-rk3588 families both use identical vendor branch settings (same KERNELSOURCE, KERNELBRANCH, and KERNELPATCHDIR), demonstrating that vendor branches are intentionally generic rather than SoC-specific.

Learning: In the Armbian build system, board family configuration files (like config/sources/families/rk35xx.conf) can inherit kernel branch definitions from common include files (like config/sources/families/include/rockchip64_common.inc). Even if a branch like "edge" is not defined directly in the family conf file, it may be available through the sourced include file.

Learning: In the Armbian build system, rk32xx and rk33xx Rockchip SoCs no longer have BSP-based (vendor) kernel branches. The rk3506 is the first 32-bit Rockchip SoC to use the vendor branch in the current codebase.

7-7: LGTM! Vendor kernel support added.

Adding "vendor" to KERNEL_TARGET enables vendor kernel builds for the Quartz64A board, which aligns with the PR objective to support rkmpp and rknpu. This change works in conjunction with the BOARDFAMILY change to rk35xx.

---

3-3: BOARDFAMILY change from "rockchip64" to "rk35xx" is correct.

RK3566 belongs to the rk35xx family. The rk35xx family configuration includes vendor kernel branch support with kernel 6.1 and patches at rk35xx-vendor-6.1, making the change appropriate for enabling vendor kernel builds as described in the PR objectives.
