* Boot Image header v2 demands a DTB be passed by default.
* We don't /need/ one at all, as we have and use a dedicated
DTB partition.
* Signing hates trying to find dtb.img anywhere for some magical
reason, so cheat and introduce a flag to include a blank one.

(cherry picked from commit fa16b42ddd1eb341f201b8d810c717ea12afe1cb)
* Remove KERNEL_LD from kernel.mk, we simply set LD in BoardConfigKernel
* Add llvm-ar in path allowlist (used by LTO)

vendor_boot v4 supports packaging multiple "fragmented" vendor ramdisks.
A secondary can be used to store the kernel modules instead of storing
them in the "normal" vendor_ramdisk.
Test: Create a vendor_boot with source built kernel/modules,
gs101 still boots.

On some devices we might want to build just the *.dtb files
that we actually need instead of the every dtb that exists.

* Currently, because DTC_EXT make flag is in the
kernel task the only way to override it is to
have TARGET_KERNEL_ADDITIONAL_FLAGS come after.

This reverts commit caa3bddf00.
Reason for revert: Breaks pixel dtbo.img build, since kernel depends on
mkdtimg. Add it back so it gets compiled and kernel can pick it up.

* AOSP build system is not aware of dtb(o) source update, and thus
won't rebuild the images, results in outdated artifact.
* Convert DTB(O)_OUT to make targets and make the images depend on them
to address the issue. This makes AOSP build system be aware of
their timestamp changes and re-execute recipes depending on them.
Finally, it's up to kernel's build system to decide actions to take.
Test: m dtb(o)image and observe dtb(o).img get rebuilt

Commit 8ac7d31 introduced this issue.
Test: run `m recoveryimage` and verify that recovery
image is now built.

* Since some time you can specify multiple configs when you prepare .config and they'll get merged to main one
* To use it inline:
TARGET_KERNEL_CONFIG := main_defconfig fragment1.config fragment2.config ...
* TARGET_KERNEL_ADDITIONAL_CONFIG has been nuked since it's superseed by this new logic
* kernelsavedefconfig will only use the base defconfig

* GCC was deprecated awhile ago, the large majority
of devices should now be using this. Clang should
be opt out as opposed to opt in.

As md5 is not considered as secure since some time, and sha256 is
industry standard, lets switch over here too.

The check for official builds now only affects the case where a prebuilt
kernel was actually used, not the case where a device builds a kernel
from source as normal.
The check has also been turned around so that it only fails the build if
it's actually an official build, not an unofficial one.

* TARGET_FORCE_PREBUILT_KERNEL should be useful when you don't have ready kernel sources (OEM releasing broken sources or releasing them lately)
* It lets you use kernel sources for userspace generated headers (generated_kernel_headers) while keeping using prebuilt kernel
* Keep in mind that generated kernel headers may not align with the ABI of kernel you're including
* This commit also partially revert commit a836d79, where TARGET_KERNEL_SOURCE would have been unset if TARGET_PREBUILT_KERNEL was defined (we already check in kernel.mk if kernel sources are present anyway)

Mini documentation:
List the names of boot modules in BOOT_KERNEL_MODULES to add them
to vendor_boot.
All modules still end up in their primary location (normally
vendor/lib/modules). Boot modules will be kept here as duplicates.
The list of boot modules is then depmod'ed and copied to the
vendor ramdisk.
The file modules.load is created from
BOARD_$(IMAGE)_KERNEL_MODULES_LOAD as the ordered list of modules
to be loaded form that location, either parsed by a modprobe script
or by init itself (only boot modules)
When using vendor_boot modules, vendor/lib/modules/modules.load
should list all modules but boot modules.
Also don't clear the output directory, because one might want to
push a modules.blocklist there.

* We're having a race with the kernel module build and vendor.img
generation, and sometimes when vendor.img wins it won't include
any modules in the image, which leads to all sorts of breakage

- The goal of specifying kernel image name was to whether kernel needs
appended dtb or not, which is not something required if the kernel is
prebuilt

* The new refactored function doesn't work with shell expanded
variables, like our $$modules.
* This is the _easy_ fix.
A proper fix would imply generating the module list into a make variable
from the shell variable, but with kati that looks unfeasable (to me...)

* A simple "make kernel" or incremental system build
always triggers a complete kernel recompilation,
even though the kernel sources were unchanged
* The reason is because .additional_config is always
considered new and invalidates the .config file,
forcing the kernel to rebuild itself every time
* Instead, prevent the /dev/null and KERNEL_OBJ dependencies
having irrelevant timestamp changes with an empty variable
* Command "make kernel" takes 3 seconds versus 40s before
