board: NanoPi R6C and R6S: Bump U-Boot from 2024.07 to 2024.10

[ColorfulRhino]

Description

Support for the NanoPi R6C and R6S has been added in v2024.10, so don't use the generic-rk3588_defconfig anymore.

Also copy relevant general patches from the 2024.07 patch folder to 2024.10.

@efectn I have bumped the R6S as well. it should work without problems, but you might want to test anyway since your R6S is a .conf board :)

How Has This Been Tested?

• ./compile.sh uboot BOARD=nanopi-r6c BRANCH=edge BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=no RELEASE=trixie
• ./compile.sh uboot BOARD=nanopi-r6s BRANCH=edge BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=no RELEASE=trixie

Cherry picked. Tested on R6C, works, incl NVMe.

The OTG port (and thus ums and rockusb etc) don't work. I've tried enabling otg stuff in DT and defconfig, but no game.
I'll PR as draft separately.

I've also re-enabled & fixed the vendor u-boot @efectn did long ago (it had a OPTEE problem since we bumped/unified against the latest radxa a few months ago). Vendor u-boot has working UMS, but no NVMe; and works best with vendor kernel and it's NPU/VPU. Will PR separately.

Thanks!

In my opinion it's best to focus all time and energy on making upstream/mainline U-Boot the best since it will always have the latest features and best longterm support from upstream devs, and in the long run the goal is to be able to drop all vendor stuff. What do you think?

I believe we can make the OTG port work on mainline U-Boot 😄
