Just now I was upgrading eMMC, and after cloning the old eMMC to the bigger new one I tried installing Debian's u-boot before removing the old eMMC, and it booted fine, with actual menu shown on built-in display. The u-boot-rockchip I installed is 2021.07~rc4+dfsg-1 from experimental. All I had to do was run `sudo u-boot-install-rockchip /dev/mmcblk2` and reboot. Haven't yet tested other things, like deep sleep, though I wouldn't be surprised if it didn't work properly. But then it wasn't working properly on BSP u-boot for me any more either, not since I started running stock Debian kernel.any news on deep sleep?
So at this point the only non-stock Debian things present on my system are WiFi firmware blobs and couple sound-related hacks, like tweaked and marked immutable alsa.state file and acpid hack for muting speakers when headphones are connected, and the only possible missing functionality that I'm aware of is deep sleep. Yay! As I mentioned before though, my setup is simple as a nail - single bootable ext4 partition starting at 16MiB, no LUKS/LVM, no separate /boot, no UEFI, no GRUB, no etc., just u-boot reading /boot/extlinux/extlinux.conf automatically generated by u-boot-menu. I don't have flash-kernel either, since I don't use separate /boot in this setup.
