armsom-sige5: add edge kernel support

[amazingfate]

Description

There is a dtb in mainline source tree, and it is usable now. Also add some patches to enable the sdio wifi, and I also update rtl8852bs for mainline kernel.
The PR of rtl8852bs is not yet merged, so I use the commit from my fork.

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.

• ./compile.sh kernel BOARD=armsom-sige5 BRANCH=edge KERNEL_CONFIGURE=no DEB_COMPRESS=xz KERNEL_BTF=yes KERNEL_GIT=shallow
• Armsom-sige5 boots fine

Checklist:

Please delete options that are not relevant.

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• My changes generate no new warnings
• Any dependent changes have been merged and published in downstream modules

Personal opinion: We shouldn’t add device tree's via patches. Rather let the autopatcher add the devicetree file from the patchfolder/dt/ with the PR just stating where it comes from. Makes it easier to modify in the future too

Walkthrough

• config/boards/armsom-sige5.csc: KERNEL_TARGET updated from "vendor" to "vendor|edge".
• config/kernel/linux-rockchip64-edge.config: Adds CONFIG_RTL8852BS=m.
• lib/functions/compilation/patch/drivers_network.sh: Extends RTL8852BS patching to rockchip64 (kernel >= 6.1), updates rtl8852bs_ver to commit 8fa9401084686a645e0a6da359610cc8fce22dc5, and adjusts Makefile platform case from rk35xx to rk35xx|rockchip64.

5-5: Edge target enabled: OK. Please source DT via autopatcher, not patching DTS/DTB directly.

Use the dt autopatcher (patchfolder/dt/) and note the upstream DTS location in the PR for easier future updates.

I can add the autopatcher entry and doc snippet if you want.

398-402: Replace inline sed hack with a tracked patch.

Move the RTW_WARN_LMT workaround into patch/misc to keep driver modifications reproducible and hashed with the kernel drivers set.

Learning: The wireless driver patches wireless-rtl8812au-Fix-6.16.patch, wireless-rtl8811cu-Fix-6.16.patch, and wireless-rtl88x2bu-Fix-6.16.patch in the Armbian build system are backward compatible and can be applied unconditionally without version checks, even though they're named for 6.16+ fixes.

Learning: Armbian kernel configuration files like linux-filogic-current.config are autogenerated overlays on top of arch defconfig. Comments added manually will be lost during future updates by maintainers, and explicit "CONFIG_OPTION is not set" statements aren't needed for mutually exclusive options since these are overlay configs that only specify changes from the base configuration.

Timestamp: 2025-07-27T15:54:35.119Z
Learning: In the Armbian build system, staging 802.11 drivers like CONFIG_RTLLIB, CONFIG_RTL8192E, CONFIG_R8712U are kept enabled alongside upstream rtw88 drivers because rtw88 is still under development and suffers from reliability issues. The staging drivers serve as necessary fallbacks when upstream drivers are unstable, prioritizing working hardware over avoiding technical conflicts.

Learning: Not all Armbian boards support all kernel versions (legacy, current, edge). Some boards may only support specific kernel versions due to hardware limitations or lack of mainline support, which is why their KERNEL_TARGET contains only the supported options (e.g., just "legacy").

Timestamp: 2025-06-25T03:42:09.086Z
Learning: In Armbian build system configuration files like config/sources/families/*.conf, KERNELSOURCE is explicitly declared when using unofficial or 3rd party kernel repositories (like the "dev" branch using https://github.com/apritzel/linux), but can be omitted when using the standard mainline kernel (like the "edge" branch) since it will fall back to the default mainline source.

Timestamp: 2025-08-02T05:46:10.664Z
Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

Learning: In Armbian build system configuration files like config/sources/families/*.conf, when KERNELSOURCE is not explicitly declared in a case branch, the system falls back to a default KERNELSOURCE value, so missing KERNELSOURCE declarations are not critical issues.

Learning: In the Armbian build system, RTL8811CU/RTL8821C wireless driver deprecation starting with kernel 6.12+ is not due to build failures but because support is being integrated into the upstream RTW88 driver. The deprecated drivers still build and function correctly during the transition period.

Learning: In the linux-rk35xx-vendor kernel, the LTE driver options (CONFIG_LTE, CONFIG_LTE_RM310, CONFIG_LTE_EM05) are defined as boolean in drivers/net/lte/Kconfig and cannot be built as modules - they must be either built-in (=y) or disabled.

366-422: Extend gating to rockchip64: LGTM.

Including rockchip64 in both the version gate and Makefile platform toggle is correct and consistent.

There is no dts added in this pr.
