The driver is actually for the Designware DWC2 controller.
This patch is the first to rename global symbol, the struct
s3c_plat_otg_data.
The rename is done automatically:
$ sed -i "s/s3c_plat_otg_data/dwc2_plat_otg_data/g" \
`git grep s3c_plat_otg_data | cut -d : -f 1`

The s3c-otg IP block is in fact a DWC2 OTG one, so finally rename the
config option to make it less misleading. No functional change, just
a mechanical change done using the following script:
git grep USB_GADGET_S3C_UDC_OTG | cut -d : -f 1 | sort -u | \
while read line ; do
sed -i "s/USB_GADGET_S3C_UDC_OTG/USB_GADGET_DWC2_OTG/g" $line ;
done

Most of the functions are local to the s3c_udc driver, remove them

As per dwc3 databook, delay is required before taking the core out of reset.
This delay is required so that the PHY are stable, and then we can take core
out of reset.
Reference is taken from linux dwc3 code, file: drivers/usb/dwc3/core.c.

This is necessary to distinguish between the "dfu-util --detach" and
the "dfu-util --reset" requests.
The default weak implementation of dfu_usb_get_reset() unconditionally
reboots the device, but we want to be able to continue the boot.scr
execution after writing the kernel, fdt and ramdisk to RAM via DFU.

Add a simple USB keyboard driver for sandbox. It provides a function to
'load' it with input data, which it will then stream through to the normal
U-Boot input subsystem. When the input data is exhausted, the keyboard stops

So far the fastboot code was only supporting MMC-backed devices for its
flashing operations (flash and erase).
Add a storage backend for NAND-backed devices.
Signed-off-by: Maxime Ripard <[email protected]>

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.

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.
