commit c3c016c "sf: Add SPI NOR protection mechanism" introduced
flash_lock()/flash_unlock()/flash_is_locked() methods for SPI flash,
but not every flash driver supplies these. We should test these
methods against NULL before actually calling them.

When converting between PCI bus and phys addresses, a two pass search
was introduced with preference to non-PCI_REGION_SYS_MEMORY regions.
See commit 2d43e873a29ca4959ba6a30fc7fb396d3fd0dccf.
However, since PCI_REGION_MEM is defined as 0, the if statement was
always asserted true: ((flags & PCI_REGION_MEM) == PCI_REGION_MEM)
This patch uses PCI_REGION_TYPE bit to check if the region is
PCI_REGION_MEM: ((flags & PCI_REGION_TYPE) == PCI_REGION_MEM)

So far the fastboot code was only supporting MMC-backed devices for its

The fastboot flash command that writes an image to a partition works in
several steps:
1 - Retrieve the maximum size the device can download through the
"max-download-size" variable
2 - Retrieve the partition type through the "partition-type:%s" variable,
that indicates whether or not the partition needs to be erased (even
though the fastboot client has minimal support for that)
3a - If the image is smaller than what the device can handle, send the image
and flash it.
3b - If the image is larger than what the device can handle, create a
sparse image, and split it in several chunks that would fit. Send the
chunk, flash it, repeat until we have no more data to send.
However, in the 3b case, the subsequent transfers have no particular
identifiers, the protocol just assumes that you would resume the writes
where you left it.
While doing so works well, it also means that flashing two subsequent
images on the same partition (for example because the user made a mistake)
would not work withouth flashing another partition or rebooting the board,
which is not really intuitive.
Since we have always the same pattern, we can however maintain a counter
that will be reset every time the client will retrieve max-download-size,
and incremented after each buffer will be flashed, that will allow us to
tell whether we should simply resume the flashing where we were, or start
back at the beginning of the partition.

Introudce a new function lcdif_power_down.
1. Waits for a VSYNC interrupt to guarantee the reset is done at the
VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?)
and helps the LCDIF work normally at the kernel stage.
2. Add power down function to stop lcdif.
The reason to introduce lcdif_power_down is that we want lcdif to be in
initial state when doing uboot reset or before kernel boot to make
system stable, otherwise system may hang.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.
