Currently u-root doesn't build for various reasons.
1. The boot cmds have changed. Some have been removed and the default
has changed to the 'boot' cmd for loading an OS.
2. The elvish shell has been removed as default shell. The gosh is now

3. For some reason the -uroot-source parameter doesn't exist anymore? So
instead we just cd into the u-root directory and build the initramfs

When starting a nested instance Make communicates information on the
number of jobs and how to synchronize difference instances via MAKEFLAGS
variable. Explicitly overwriting it when invoking
payloads/external/iPXE/Makefile ends up forcing serial build of iPXE.
iPXE builds hundreds of files and its dependency generation is done
separately from compilation making the whole process take couple minutes
on a single CPU (which becomes several seconds if large enough number of
CPUs is available).
iPXE seems to have Make-based build system that has no problems with
parallel build and not utilizing that effectively turns it into a
bottleneck when building a coreboot image in parallel.
It's unclear whether MAKEFLAGS= was even added for any particular
purpose. It doesn't prevent child instances from using variables of
parents, nor it prevents child instance from running in parallel
(because it's still passed as an environment variable that's processed
prior of variable assignments on command-line), but it does prevent
grandchild instance from running in parallel (actual iPXE's Makefile).
MFLAGS contains flags from MAKEFLAGS and isn't used implicitly by Make,
so no need to clear it either because iPXE doesn't use it.

This adds another external payload to coreboot. The payload has been
heavily based on u-boots UEFI implementation.
The leanefi payload is basically a translator from coreboot to UEFI. It
takes the coreboot tables and transforms them into UEFI interfaces.
Although it can potentially load any efi application that can
handle the minimized interface that leanefi provides, it has only
been tested with LinuxBoot (v6.3.5) as a payload. It has been optimized
to support only those interfaces that Linux requires to start.
Among other leanefi does not support:
- efi capsule update (also efi system resource table)
- efi variables
- efi text input protocol (it can only output)
- most boot services. mostly memory services are left (e.g. alloc/free)
- all runtime services (although there is still a very small runtime
footprint that is planned to be removed in the near future)
- TCG2/TPM (although that is mostly because of laziness)
The README.md currently provides more details on why.
The payload currently only supports arm64 and has only been tested
on emulation/simulator targets. The original motivation was to get ACPI
on arm64 published to the OS without using EDK2. It is however also
possible to supply the leanefi with a FDT that is published to the OS.
At that point one would however probably use coreboot only instead of
this shim layer on top. It would be way nicer to have Linux support
something else than UEFI to propagate the ACPI tables, but it requires
to get the Linux maintainer/community on board. So for now this shim
layer ciruimvents that.
LBBR Test:
// 1. dump FDT from QEMU like mentioned in aarch64 coreboot doc
// 2. compile u-root however you like (aarch64)
// 3. compile Linux (embed u-root initramfs via Kconfig)
// 4. copy Linux kernel to payloads/leanefi/Image
// 5. copy following coreboot defconfig to configs/defconfig:
CONFIG_BOARD_EMULATION_QEMU_AARCH64=y
CONFIG_PAYLOAD_NONE=n
CONFIG_PAYLOAD_LEANEFI=y
CONFIG_LEANEFI_PAYLOAD=y
