Currently u-boot fastboot can only send one message back to host,
so if there is a need to print more than one line messages must be
kept sending until all the required data is obtained. This behavior
can be adjusted using multiresponce ability (getting multiple lines

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
This should be removed by:
https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11
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"
Add some functions which provide an argument to a command, or NULL if
the argument does not exist.
Use the same numbering as argv[] since it seems less confusing than the
previous idea.

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.

child nodes representing individual LEDs. This means that the drivers
whose .probe methods rely on this were broken by commit 83c63f0d11
("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 0107469780 ("led: gpio: Use NOP uclass driver for top-level
node") and commit 910b01c27c ("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
e3aa76644c ("led: gpio: Check device compatible string to determine
the top level node") did for gpio_led, but that fix was then supplanted
by commit 0107469780 ("led: gpio: Use NOP uclass driver for top-level
node")
Fixes: 83c63f0d11 ("led: Move OF "label" property parsing to core")

If the driver's own .bind method has populated uc_plat->label, don't
override that. This is necessary for an upcoming driver for ti,lp5562,
where the DT binding unfortunately says to use "chan-name" and not
"label".

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";
...
};
...
mbox_n: mailbox@n {
compatible = "xlnx,zynqmp-ipi-dest-mailbox";
...
}
};
Then mailbox client uses child mailbox node as following:
ipi-dest-1 {
...
mboxes = <mbox_1 0>, <mbox_1 1>;
mbox-names = "tx", "rx";
...
};
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.
This way multiple mailbox agents are supported in device-tree without breaking
previous binding support.

The current implementation may cause BUG_ON() in blkfront_aio()
BUG_ON(n > BLKIF_MAX_SEGMENTS_PER_REQUEST);
In pvblock_iop(), a read/write operation will be split into smaller
chunks of data so that the size in one access (aio_nbytes) is limited
to, at the maximum,
BLKIF_MAX_SEGMENTS_PER_REQUEST * PAGE_SIZE
But this works only if when the *buffer* passed in to pvblock_io()
is page-aligned. If not, the given data region may stand across
(BLKIF_MAX_SEGMENTS_PER_REQUEST + 1) pages. See the logic in
blkfront_aio():
start = (uintptr_t)aiocbp->aio_buf & PAGE_MASK;
end = ((uintptr_t)aiocbp->aio_buf + aiocbp->aio_nbytes +
PAGE_SIZE - 1) & PAGE_MASK;
Then this will lead to BUG_ON() above.
This can be fixed by decreasing the maximum size of aio_nbytes.

To quote the author:
The show_board_info() function was adjusted to weak so that it could be
entirely replaced with a board-specific implementation.
The intended way for boards to provide their own information is via a
sysinfo driver. But currently there is no way to show anything other
than the model name.
This series adds support for showing a few more items, in a way that is
easy for boards to extend.
Since there is already a weak checkboard() function, we don't need to
have two levels of weak function here. So this series drops the weak
attribute from show_board_info()
Existing boards will see a slight change in output, in that the model
name will appear first, before any custom output. If that is a problem,
then the solution is to implement a sysinfo driver for the board.
At present only the model name is shown on start. Some boards want to
display more information. Add some more options to allow display of the
manufacturer as well as the version and date of any prior-stage
firmware.
This is useful for coreboot, at least. If other boards have more
information to display, it is easy to add it, now.

Today CMD_BIND defaults to 'y' when USB_ETHER is enabled. In practice,
CMD_BIND should default to 'y' when any USB gadget is enabled not only
USB_ETHER. Let's invert the logic of the dependency and use the weak
'imply' keyword to enforce this.

Exit the UMS handler loop in case START-STOP UNIT SCSI command is
received. This is sent e.g. by the util-linux eject(1) command and
indicates to the device that it is supposed to spin down the media
and enter low power state.
This effectively adds support for exitting the 'ums' command from
host using 'eject /dev/sdN' that is on par with 'dfu-util -e' .

Add CONFIG_DFU_NAME_MAX_SIZE to change the proper size.
If name is longer than default size, it can do wrong behavior during updating
image. So it need to change the proper maximum size.
This patch is proviced the solution to change value with configuration.

The ChipIdea device controller wasn't properly cleaned up when disabled.
So enabling it again left it in a broken state. The problem occurred for
example when the host unbinds the driver and binds it again.
During the first setup, when the out request is queued, the endpoint is
primed (`epprime`). If the endpoint is then disabled, it stayed primed
with the initial buffer. So after the endpoint is re-enabled, the device
controller and device driver were out of sync: the new out request was
in the driver queue head, yet not submitted, but the "complete" function
was still called, since the endpoint was primed with the old buffer.
With the fastboot function this error led to the (rather confusing)
error message "buffer overflow".
Fixed by clearing the primed buffers with the `epflush` (`ENDPTFLUSH`)
register.

SCSI device scan code was executing TEST UNIT READY command without
explicitly setting dma direction in struct scsi_cmd to NONE, so command
was passed to driver with dma direction set to DMA_FROM_DEVICE,
inherited from older usage.
With WDC SDINDDH6-64G ufs device, that caused TEST UNIT READY to
return error.
Fix that, by explicitly setting dma direction to NONE for
TEST UNIT READY, and restoring it back DMA_FROM_DEVICE for the
following READ CAPACITY.

According to the virtio v1.x "entropy device" specification, a virtio-rng
device is supposed to always return at least one byte of entropy.
However the virtio v0.9 spec does not mention such a requirement.
The Arm Fixed Virtual Platform (FVP) implementation of virtio-rng always
returns 8 bytes less of entropy than requested. If 8 bytes or less are
requested, it will return 0 bytes.
This behaviour makes U-Boot's virtio_rng_read() implementation go into an
endless loop, hanging the system.
Work around this problem by always requesting 8 bytes more than needed,
but only if a previous call to virtqueue_get_buf() returned 0 bytes.
This should never trigger on a v1.x spec compliant implementation, but
fixes the hang on the Arm FVP.
