cb32266d4a video: Allow console output to be silenced
When using expo we want to be able to control the information on the
display and avoid other messages (such as USB scanning) appearing.

Add a 'quiet' flag for the console, to help with this.

The test is a little messy since stdio is still using the original
vidconsole create on start-up. So take care to use the same.

4ca87fd18c Merge patch series "Qualcomm: cleanup OF_LIVE fixup and fix RB1/2"
Caleb Connolly <caleb.connolly@linaro.org> says:

Introduce a new event to signal that the live tree has been built,
allowing boards to perform fixups on the tree before devices are bound.
Crucially this allows for devices to be enabled or disabled, but also
allows for properties that are parsed during the bind stage to be
modified (such as dr_mode for dwc3).

With this in place, mach-snapdragon is switched over to use the event
and some hacky U-Boot specific DT overrides (which had to be undone
prior to booting an image) are removed in favour of fixing up the
livetree (which is not passed on to further boot stages).

Finally, some minor fixes are made for the QCM2290 RB1 board, the sdcard
is enabled and it now uses USB host mode in U-Boot like it's bigger
sibling the RB2.

3b983cf48e mach-snapdragon: of_fixup: set dr_mode for RB1/2 boards
The RB1 and RB2 have a single USB controller which is manually muxed
between a type-c port and an internal USB hub via a DIP switch. OTG is
supported in Linux, but the DWC3 driver in U-Boot can only handle a
single mode, and defaults to peripheral mode.

We did hack around this on the RB2, but the RB1 got left out.

Now that we can fix up the live tree before devices are bound, drop the
DTS hacks and do the fixup at runtime instead.

993a9db918 event: signal when livetree has been built
OF_LIVE offers a variety of benefits, one of them being that the live
tree can be modified without caring about the underlying FDT. This is
particularly valuable for working around U-Boot limitations like lacking
USB superspeed support on Qualcomm platforms, no runtime OTG, or
peripherals like the sdcard being broken (and displaying potentially
worrying error messages).

Add an event to signal when the live tree has been built so that we can
apply fixups to it directly before devices are bound.

2a61f40d4a video: Enable VIDEO_DAMAGE for drivers that need it
Some drivers call video_set_flush_dcache() to indicate that they want to
have the dcache flushed for the frame buffer. These drivers benefit from
our new video damage control, because we can reduce the amount of memory
that gets flushed significantly.

This patch enables video damage control for all device drivers that call
video_set_flush_dcache() to make sure they benefit from it.

369c6a6c35 video: Always compile cache flushing code
The dcache flushing code path was conditional on ARM && !DCACHE config
options. However, dcaches exist on other platforms as well and may need
clearing if their driver requires it.

Simplify the compile logic and always enable the dcache flush logic in
the video core. That way, drivers can always rely on it to call the arch
specific callbacks.

This will increase code size for non-ARM platforms with CONFIG_VIDEO=y
slightly.

70dfd67478 video: Use VIDEO_DAMAGE for VIDEO_COPY
CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we
print a single character, it will always copy the full range of bytes
from the top left corner of the character to the lower right onto the
uncached frame buffer. This includes pretty much the full line contents
of the printed character.

Since we now have proper damage tracking, let's make use of that to reduce
the amount of data we need to copy. With this patch applied, we will only
copy the tiny rectangle surrounding characters when we print them,
speeding up the video console.

After this, changes to the main frame buffer are not immediately copied
to the copy frame buffer, but postponed until the next video device
sync. So issue an explicit sync before inspecting the copy frame buffer
contents for the video tests.

98a898e584 mtd: mtdpart: Support MTDPART_SIZ_FULL in fixed-partitions
Flash partitions may specify MTDPART_SIZ_FULL (=0) as the size of the
partition to indicate "the remainder of the flash". Make this work with
device-tree "fixed-partitions" as well.

This makes MTD partitioning compatible with the Linux kernel, see:
  https://github.com/torvalds/linux/blob/master/include/linux/mtd/partitions.h#L29
  https://github.com/torvalds/linux/blob/master/drivers/mtd/mtdpart.c#L123

Previously, this could only be done through MTDPARTS so this change allows
boards like topic_miami to migrate from `mtdparts`/`mtdids` to devicetree
partitions.

aa96cda0a5 clk: fix crash on clk_set_rate clean rate cache
It's currently possible to make the bootloader crash on calling
clk_set_rate caused by the loop in clk_clean_rate_cache.

The loop assume that every child of the clock node are also clock
device but this is not always the case. For example it's common for a
clock to bind to a reset device or also expose a syscon if the clock
register map is also used to apply special configuration.

In such case, on accessing a device as a clock, the bootloader crash. To
correctly handle this, check if the child device is actually a clock and
ignore otherwise.

f59cb6a697 Revert "mtd: spi-nor: Remove recently added SST special case"
SST(sst26wf016) flashes have multiple erase block sizes, including
8 KB, 32 KB, and 64 KB. Since a 64 KB sector erase cannot be performed
on all blocks, the 4 KB sector erase command should be used instead.
Enabling the SPI_FLASH_USE_4K_SECTORS configuration allows the use of
4 KB sector erases, but it may increase the erase operation time for large
memory flashes.

This reverts commit 34cd4a72fb

MEMORY ORGANIZATION:
The SST26WF016B/016BA SQI memory array is organized
in uniform, 4 KByte erasable sectors with the following
erasable blocks: eight 8 KByte parameter, two
32 KByte overlay, and thirty 64 KByte overlay blocks.
See Figure 3-1.

c0ed43c2a9 drivers: spi: Fix data loss issue in QSPI
QSPI driver performs chip select operation before every read/write
access. During this operation, driver needs to enable and disable
the QSPI controller. This may cause data loss if there is inadvertent
halting of any ongoing read/write operation. To avoid this scenario,
waiting for the QSPI status to be idle before next read/write
operation is implemented.
