- you can download prebuilt kernel releases from actions
- kernel configs from here are made to boot with u-boot EFI, you can use some efi bootmanager like systemd-boot for them as well
- preferable to have storage gpt-partitioned with ESP FAT32 /boot/efi partition and (must?) to have u-boot on SPI to use EFI boot
- if you don't use u-boot EFI you have to disable
CONFIG_EFIkernel config, or use release prefixed withnon-efi - my config additions are listed in config_diff_from_official.txt
- armbian u-boot should work, refer to u-boot directory to build it manually
- toolchain used: https://mirrors.edge.kernel.org/pub/tools/llvm/files
- some auxiliary tools you can find in misc directory
- clone this repo to ~/kernel-patches
