Patches are from the Linux Rockchip Mailing List, submitted by Alexey
Charkov. [1]
Notable improvements from changelog:
- Moved the TSADC enablement to per-board .dts/.dtsi files
- Dropped extra "inefficient" OPPs (same voltage - lower frequencies)
- Dropped second passive cooling trips altogether to keep things simple
- Added a cooling map for passive GPU cooling (in a separate patch)
- Added regulator coupling for EVB1 and QuartzPro64
Also enable automatic fan control on Rock 5B.

"general-add-overlay-compilation-support.patch" became obsolete in
Linux 6.9 (see AR-2352 [1]). Fix this problem:
- Rename *.dts sources in overlay directory to *.dtso
- Change "target +=" line to "dts-y +=" in overlay Makefile
- Remove "always +=" line in overlay Makefile
- Add .scr compilation support in kernel scripts/Makefile.lib
- Patch kernel scripts/Makefile.dtbinst to avoid flattening overlay
directory
For the last two points, see
general-add-overlay-compilation-support.patch

- Bump mainline kernel from 6.10-rc1 to 6.10-rc2
- Remove patches which are now mainlined
- Re-number "fix-initial-PERST-GPIO-value" patch as per number
ordering seen in 0000.patching_config.yaml
- Rewrite kernel config
- `common_defaults_for_mainline` already sets KERNELPATCHDIR='archive/s5p6818-4.14' thus this symlink is not necessary
- 1 step closer to a clean `patch/kernel` dir, when we could finally get rid of `archive/`
- add `pre_config_uboot_target` hook for switching BOOTCONFIG across the two targets
- adapt `UBOOT_TARGET_MAP` to not call the defconfig Makefile targets directly, instead, just do a variable assignment (ignored by Make)
- otherwise, when using the defconfig directly in the `UBOOT_TARGET_MAP`, the `post_config_uboot_target` .config changes are overwritten when Make is called
- only patch left is boot usb-nvme-scsi/sata first (still done in meson64.h)
- remove FIP handling from family file `meson-sm1.conf` into board file hook where it belongs
- u-boot: enable more compression methods, EFI debugging, i2c, leds, tcp networking
- use flashcp for mtd writing
- Unchanged:
- confirmed as of v2024.04: using the C4 (not HC4) defconfig is still needed to be able to write to mtd when booted from SD
- also confirmed: one still needs to erase Petitboot using Petitboot, then boot from SD, to be able to flash mainline u-boot to mtd

- makes it compatible with vendor out-of-box blobs (which include TEE) in the from-factory eMMC
- Armbian itself doesn't ship TEE blobs
- when combining from-factory eMMC blobs with an Armbian SD card, TEE blobs are in practice found by u-boot
- but then proceeds to fail with `optee api revision is too low`
- disable OPTEE in defconfig fixes it, TEE isn't used in any way by Armbian

uboot default behaviour is the assert resets when
it has to pass control to the kernel.
This may cause compatibility issues if the kernel
driver is not instructed to properly deassert the resets,
so we change the uboot behaviour for dwc and ehci usb
drivers to deassert reset on exit.
multitool utility uses the legacy/vendor 4.4 kernel
and it was failing to turn on HDMI properly.
Assert and deassert all vop and hmdi resets to clean
up the state on uboot exit seems to solve the issue
