Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"
To quote the author:
It would be useful to be able to boot an OS when CONFIG_CMDLINE is
disabled. This could allow reduced code size.
Standard boot provides a way to handle programmatic boot, without
scripts, so such a feature is possible. The main impediment is the
inability to use the booting features of U-Boot without a command line.
So the solution is to avoid passing command arguments and the like to
code in boot/
A similar process has taken place with filesystems, for example, where
we have (somewhat) separate Kconfig options for the filesystem commands
and the filesystems themselves.
This series starts the process of refactoring the bootm logic so that
it can be called from standard boot without using the command line.
Mostly it removes the use of argc, argv and cmdtbl from the internal
logic.
Some limited tidy-up is included, but this is kept to smaller patches,
rather than trying to remove all #ifdefs etc. Some function comments
are added, however.
A simple programmatic boot is provided as a starting point.
This work will likely take many series, so this is just the start.
Size growth with this series for firefly-rk3288 (Thumb2) is:
arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0
but it is not included in this series as it is already large enough.
No functional change is intended in this series.
Changes in v3:
- Add a panic if programmatic boot fails
- Drop RFC tag
Changes in v2:
- Add new patch to adjust position of unmap_sysmem() in boot_get_kernel()
- Add new patch to obtain command arguments
- Fix 'boot_find_os' typo
- Pass in the command name
- Use the command table to provide the command name, instead of "bootm"

Merge patch series "some LED patches"
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.

led-uclass: do not create fallback label for top-level node
Many existing drivers, and led-uclass itself, rely on uc_plat->label
being NULL for the device representing the top node, as opposed to the
child nodes representing individual LEDs. This means that the drivers
whose .probe methods rely on this were broken by commit 83c63f0d1185
("led: Move OF "label" property parsing to core"), and also that the top
node wrongly shows up with 'led list'.
Binding the same driver to the top node as to the individual child
nodes is arguably wrong, and the approach of using a UCLASS_NOP driver
for the top node is probably better - this has for example been done in
commit 01074697801b ("led: gpio: Use NOP uclass driver for top-level
node") and commit 910b01c27c04 ("drivers: led: bcm6753: do not use null
label to find the top")
Until remaining affected drivers are fixed, we can use a heuristic
that only sets the label to the fallback value derived from the node
name if the node does not have a "compatible" property - i.e., if it
has been bound to the LED driver explicitly via
device_bind_driver_to_node(). This is similar to what commit e3aa76644c2a ("led: gpio: Check device compatible string to determine
the top level node") did for gpio_led, but that fix was then supplanted
by commit 01074697801b ("led: gpio: Use NOP uclass driver for top-level

mailbox: zynqmp: support mulitple mboxes via device-tree
As of now only one mailbox agent is supported by mailbox driver.
On zynqmp platform there are about 7 mailbox agents which can communicate
over same IPI channel to U-Boot. This patch series introduces new
"zynqmp_ipi_dest" driver which adds one to multi-channel mailbox
support.
Following format in device-tree is expected as per latest bindings:
zynqmp-ipi {
compatible = "xlnx,zynqmp-ipi-mailbox";
mbox_1: mailbox@1 {
/* New compatible for child node */
compatible = "xlnx,zynqmp-ipi-dest-mailbox";
...

New "zynqmp_ipi_dest" driver is for devices with
"xlnx,zynqmp-ipi-dest-mailbox" compatible string. This driver will take care
of mailbox send recv ops and it replaces previous "zynqmp_ipi" driver.
Now "zynqmp_ipi" driver simply binds each child device with "zynqmp_ipi_dest"
driver.
However, its important to maintain backward comaptibility with previous
bindings where child node does not have compatible string. In such case, new
driver isn't probed by U-Boot during boot and system fails to boot. To
resolve this issue firmware-zynqmp.c driver probes all the IPI parent node
driver which binds each child node device with "zynqmp_ipi_dest" driver.
This makes sure corresponding child driver will be
probed when requested using mbox_get_by_name or mbox_get_by_idx
framework calls.
