10c398d6e4 treewide: Tidy up semicolon after command macros
The U_BOOT_CMD_COMPLETE() macro has a semicolon at the end, perhaps
inadvertently. Some code has taken advantage of this.

Tidy this up by dropping the semicolon from the macro and adding it to
macro invocations as required.

bfe3c7b93b 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.

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.

f9dc67d18e led: add TI LP5562 LED driver
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.

067e4ce35b 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 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")

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".

On powerpc, stack protector expects a function called
__stack_chk_fail_local() instead of __stack_chk_fail()

And some versions of GCC for powerpc default to TLS canary
instead of global canary, so always force GCC to use global
canary with -mstack-protector-guard=global

654580eee1 xen: pvblock: fix the maximum io size in one operation
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.
