- share a single `.git` for all u-boots
- all fetches are done against it, maximizing cache hit ratio drastically
- also reduces the size of each working copy by more than 70%
- split uboot's git stuff into uboot-git.sh
- split `uboot_prepare_git()` from `compile_uboot()`
- now we've a single `.git` for all kernels with all branches; a "master" cache
- back to full stable git bundle usage from kernel.org
- bye bye, "gitballs"
- split kernel-related git stuff into `kernel-git.sh`
- introduce `ARMBIAN_MOUNTPOINTS_DEPRECATED` @TODO actually use for cleaning non-Docker
- add `axel` hostdep for multi-conn download of bundle, which comes from a CDN.
- deprecate old mountpoints for gitballs and linux-kernel
- move cleaning of old sources/kernel to mountpoints code
- introduce `if_user_on_terminal_and_not_logging_add()`;
- also the opposite, `if_user_not_on_terminal_or_is_logging_add()`
- unset `CURRENT_LOGGING_SECTION` when exiting a logging section
- introduce `do_with_logging_unless_user_terminal()`
- sharing most UEFI code, will replace the `virtual` one soon
- x86: patch uboot defconfig to use the `q35` machine type, not `i440fx`
- separate x86 bootscript, due to non-uInitrd-ness of it
- hack ramdisk load address both in u-boot source and bootscript
- use 32-bit u-boot, not 64-bit
- grub: introduce `UEFI_GRUB=skip`, does not deploy GRUB (but does the kernel packages, etc)
- auto-enable qcow2 output for these
- works with both distro's and Armbian's kernels
- cli builds won't have PPAs and other external repos
- packages from such repos should be listed in `packages.external` now, so they're not mismatched
- `PACKAGE_LIST_EXTERNAL` (packages.external) only in DESKTOP builds
- this logic may change later, example:
- we might _also_ want pure-Ubuntu desktops, without external repos
- we might _instead_ want external repos in the cli builds
- this way is easy to change, since everything is kept separate and we can change in a single place.
- introduce `SHOW_CCACHE=yes` for detailed ccache statistics and logging
- fix: kernel build is done under "env -i", so pass CCACHE_DIR down to Make if CCACHE_DIR is set...
- split from kernel.sh, show stats also for u-boot targets; show compile time
- add volume definition (under `${SRC}/cache/ccache`); auto-use that in Docker builds via `CCACHE_DIR`
- better logging for `do_with_ccache_statistics()`
- there's some CCACHE_DIR code from before; unify @TODO
- `undecided` now directly sends to `build`, which might send to `docker`, which relaunches `build` in Docker;
- the _sending to Docker_ part probably needs refactor
- DEBUG_EXTENSION_CALLS is gone. use SHOW_EXTENSIONS instead.
- LOG_ALL_HOOK_TRACES is gone. use SHOW_EXTENSIONS_TRACE instead
- LOG_ENABLE_EXTENSION is gone. use SHOW_DEBUG=yes instead
- Changes how Docker Desktop works too, there's a `case` for switching back if needed.
- Now the linux-only CONTAINER_COMPAT hacks are used also for Darwin (`DOCKER_SERVER_REQUIRES_LOOP_HACKS=yes`)
- `/dev/loop*` is spelled out since they don't exist on Darwin (`DOCKER_SERVER_USE_STATIC_LOOPS=yes`)
