##### METHOD=armbian; Foreign kernels, taken from Armbian's OCI repos. Those are "exotic" kernels for certain SoC's.
#                    edge = (release candidates or stable but rarely LTS, more aggressive patching)
#                    current = (LTS kernels, stable-ish patching)
#                    vendor/legacy = (vendor/BSP kernels, stable patching, NOT mainline, not frequently rebased)
#                    Check https://github.com/orgs/armbian/packages?tab=packages&q=kernel- for possibilities
#                    nb: when no ARMBIAN_KERNEL_VERSION, will use the first tag returned, high traffic, low cache rate.
#                        one might set eg ARMBIAN_KERNEL_VERSION='6.7.10-xxxx' to use a fixed version.
