Simon Glass <sjg@chromium.org> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.

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.

The driver currently requires the bit clock divider be hardcoded in
devicetree (or use the hardcoded default from apq8016).
The bit clock divider is used to derive the baud rate from the core
clock:
baudrate = clk_rate / csr_div
clk_rate is the actual programmed core clock rate which is returned by
clk_set_rate(), and this UART driver only supports a baudrate of 115200.
We can therefore determine the appropriate value for UARTDM_CSR by
iterating over the possible values and finding the one where the
equation above holds true for a baudrate of 115200.
Implement this logic and drop the non-standard DT bindings for this
driver.

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.
Driver for the TI LP5562 4 channel LED controller. Supports
independent on/off control of all 4 channels. Supports LED_BLINK on 3
independent channels: blue/green/red. The white channel can blink, but
shares the blue channel blink rate.
Heavily based on patch originally from Doug Zobel [1].
I have modified it so it matches the DT bindings in the linux tree,
and also follows the linux driver implementation more closely. This
should address Tom's concerns, and also matches my goal of making the
U-Boot driver work with our existing .dts which is known to work in
linux.
As our boards only have the R,G,B outputs connected, I have not
actually tested how the white channel behaves, but the R,G,B work
exactly as expected.

Add a sandbox NAND flash driver to facilitate testing. This driver supports
any number of devices, each using a single chip-select. The OOB data is
stored in-band, with the separation enforced through the API.
For now, create two devices to test with. The first is a very small device
with basic ECC. The second is an 8G device (chosen to be larger than 32
bits). It uses ONFI, with the values copied from the datasheet. It also
doesn't need too strong ECC, which speeds things up.
Although the nand subsystem determines the parameters of a chip based on
the ID, the driver itself requires devicetree properties for each
parameter. We do not derive parameters from the ID because parsing the ID
is non-trivial. We do not just use the parameters that the nand subsystem
has calculated since that is something we should be testing. An exception
is made for the ECC layout, since that is difficult to encode in the device
tree and is not a property of the device itself.
Despite using file I/O to access the backing data, we do not support using
external files. In my experience, these are unnecessary for testing since
tests can generally be written to write their expected data beforehand.
Additionally, we would need to store the "programmed" information somewhere
(complicating the format and the programming process) or try to detect
whether block are erased at runtime (degrading probe speeds).
Information about whether each page has been programmed is stored in an
in-memory buffer. To simplify the implementation, we only support a single
program per erase. While this is accurate for many larger flashes, some
smaller flashes (512 byte) support multiple programs and/or subpage
programs. Support for this could be added later as I believe some
filesystems expect this.
To test ECC, we support error-injection. Surprisingly, only ECC bytes in
the OOB area are protected, even though all bytes are equally susceptible
to error. Because of this, we take care to only corrupt ECC bytes.
Similarly, because ECC covers "steps" and not the whole page, we must take
care to corrupt data in the same way.
