Android boot flow is a bit different than a regular Linux distro.
Android relies on multiple partitions in order to boot.
A typical boot flow would be:
1. Parse the Bootloader Control Block (BCB, misc partition)
2. If BCB requested bootonce-bootloader, start fastboot and wait.
3. If BCB requested recovery or normal android, run the following:
3.a. Get slot (A/B) from BCB
3.b. Run AVB (Android Verified Boot) on boot partitions
3.c. Load boot and vendor_boot partitions
3.d. Load device-tree, ramdisk and boot
The AOSP documentation has more details at [1], [2], [3]
This has been implemented via complex boot scripts such as [4].
However, these boot script are neither very maintainable nor generic.
Moreover, DISTRO_DEFAULTS is being deprecated [5].
Add a generic Android bootflow implementation for bootstd.
For this initial version, only boot image v4 is supported.

Use upstream device tree files and bindings. To do so:
- imply (enable) OF_UPSTREAM option for E850-96 target
- point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts
- remove now not needed local dts files, binding docs and headers
- update MAINTAINERS and board/samsung/e850-96/MAINTAINERS
correspondingly
Upstream device tree files for Exynos850 SoC and E850-96 board are
pretty much the same as local (removed) ones, so the conversion is
rather straightforward and painless in this case. The appended dts file
(arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged.
The only remaining local dt-bindings doc for E850-96 board is
exynos-pmu.yaml. It wasn't removed as it's quite different from Linux
kernel version. Particularly U-Boot local version of exynos-pmu.yaml
describes "samsung,uart-debug-1" property, which is not present in Linux
kernel binding. Later it might be upstreamed to Linux kernel, and once
it's done the U-Boot exynos-pmu.yaml binding can be removed.
No functional change.

Sughosh Ganu <sughosh.ganu@linaro.org> says:
The following patch series adds support for version 2 of the FWU
metadata. The version 2 metadata structure is defined in the latest
revision of the FWU specification [1].
The earlier versions of these patches were migrating to a version 2
only support in U-Boot, similar to TF-A. However, based on feedback
from ST [2], this series has been updated to support both versions. A
platform would still be needed to enable one of the two versions of
metadata through a config symbol.
TF-A has code which reads the FWU metadata and boots the platform from
the active partition. TF-A has decided to migrate the FWU code to a
version 2 only support. These changes have been merged in upstream
TF-A.
These changes have been tested on the ST DK2 board, which uses the GPT
based partitioning scheme. Both V1 and V2 metadata versions have been
tested on the DK2 board.
These changes need to be tested on platforms with MTD partitioned
storage devices.
Add an entry for the FWU Multi Bank Update feature.

Greg Malysa <greg.malysa@timesys.com> says:
This series adds support for the ADI SC5xx machine type and includes two
core drivers that are required for being able to boot any board--a UART
driver, the gptimer driver which is used as a clock reference (CNTVCNT
is not supported on the armv7 sc5xx SoCs) and the clock tree driver. Our
corresponding Linux support relies on u-boot configuring the clocks
correctly before booting, so it is not possible to boot any board
without the CGU/CDU configuration happening here. There are also no
board files, device trees, or defconfigs included here, but some common
definitions that will be used to build board files currently are. The
sc5xx SoCs themselves include many armv7 families (sc57x, sc58x, and
sc594) all using an ARM Cortex-A5, and one armv8 family (sc598) indended
to be a drop-in replacement for the SC594 in terms of peripherals, with
a Cortex-A55 instead.
Some of the configuration code in dmcinit and clkinit is quite scary and
causes a lot of checkpatch violations. It is modified from code
initially provided by ADI, but it has not been fully rewritten. There's
a question of how important it is to clean up this code--it has some
quality violations, but it has been in use (including in production) for
over two years and is known to work for performing the low level SoC
initialization, while a rewrite might introduce timing or sequence bugs
that could take a significant amount of time to detect in the future.
This adds support for the SC5XX clock trees which are required for reading
clock speeds on the SoCs. This is largely a port of the same support for
Linux, which has not yet been submitted upstream.

To quote the author:
I wanted to add support for ti,lp5562, and found an old submission
from Doug. While trying to modify that to work in current U-Boot, I
found a problem with the "move label handling to core" patches.
Patch 1 is a prerequisite for the ti,lp5562 driver, which turned out
to be needed by Christian as well.
Patch 2 is an attempt at (quick-)fixing the mentioned "move label
handling to core" problem. The real fix consists of changing remaining
drivers to not bind the same driver to the top node as to the child
nodes, but I can't test those other drivers.
Patch 3 introduces a helper which should allow removing some
boilerplate in most individual drivers, and 4,5 apply that in the gpio
and pwm drivers. Converting remaining drivers is trivial, but left out
for now.
Finally patch 6 is the reworked lp5562 driver. While I've changed it
to match existing DT bindings (with the goal of making it work with
our .dts that is known to work with the linux driver), most of the
logic is unchanged from Doug's original patch, so he is still listed
as author.
Changes in v2: Interchange order of patches 1 and 2, add a few R-bs,
and try to trim down the commit message in patch 2.
