When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

This patch fixes situation when one would like to write large file into
medium with the file system (fat, ext4, etc).
This change sets file size limitation to the DFU internal buffer size.
Since u-boot is not supporting interrupts and seek on file systems, it
becomes challenging to store large file appropriately.
To reproduce this error - create large file (around 26 MiB) and sent it
to the target board.
Lets examine the flow of USB transactions:
0. DFU uses EP0 with 64B MPS [Max Packet Size]
1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions
2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent
from target board - IN transaction
(target->PC)
3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero
Length Packet]
Now the interesting part starts:
4. OUT (PC->target) Setup transaction (request to share DFU state)
5. IN (target->PC) - reply the current DFU state
- In the UDC driver the req->completion (with dfu_flush) is called
after successful IN transfer.
- The dfu_flush() (called from req->completion callback) saves the
whole file at once (u-boot doesn't support seek on fs).
Such operation takes considerable time. When the file
is large - e.g. 26MiB - this time may be more than 5 seconds.
6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush()
writes data to eMMC memory.
The dfu-util application has hard coded timeout on USB transaction
completion set to 5 seconds (it uses libusb calls).
When the file to store is large (e.g. 26 MiB) the time needed to write it
may excess the dfu-util timeout and following error message will be displayed:
"unable to read DFU status" on the HOST PC console.
This change is supposed to leverage DFU's part responsible for storing files
on file systems. Other DFU operations - i.e. raw/partition write to NAND and
eMMC should work as before.
The only functional change is the error reporting. When dfu_flush() fails
the u-boot prompt will exit with error information and dfu-util application
exits afterwards as well.

- Trats (Exynos4210) - test for regression - eMMC, raw,

There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an

Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.
By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.
Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.
It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.
Example usage:
1. -e (detach) switch
dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e
access to u-boot prompt.
2. -R (reset) switch
dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage
