g_dnl_register: failed!, error: -19
exit not allowed from main input shell.
=> fastboot 0
g_dnl_register: failed!, error: -22

Despite that 0 is correct index for USB controller, "fastboot 0" command

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.

- Odroid XU3 (Exynos5433) - test with large file
- Trats (Exynos4210) - test for regression - eMMC, raw,

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 <maxime.ripard@free-electrons.com>
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.

usb: gadget: remove incorrect __init/__exit annotations
A recent change introduced a link error for the composite
printer gadget driver:
`printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o
Evidently the unbind function should not be marked __exit here,
because it is called through a callback pointer that is not necessarily
discarded, __composite_unbind() is indeed called from the error path of
composite_bind(), which can never work for a built-in driver.
Looking at the surrounding code, I found the same problem in all other
composite gadget drivers in both the bind and unbind functions, as
well as the udc platform driver 'remove' functions. Those will break
if anyone uses the 'unbind' sysfs attribute to detach a device from a
built-in driver.
This patch removes the incorrect annotations from all the gadget
drivers.

The ci_udc driver request allocation assumes that the endpoint descriptor
pointer is set to retrieve the endpoint number, but that is only true
when the endpoint is enabled. This results in a NULL ptr dereference
which for me happens to return 0 value. This causes the EP0 request
struct to be returned for other endpoints. Some gadget drivers like
fastboot and USB MS work fine, but ethernet does not.
Really, the ci_udc driver is the oddball here doing this EP0 special
case handling Stephen added. All the other drivers alloc/free functions
are pretty much the same with the only variation being the size of the
private struct. This could all be consolidated to a common function.

FASTBOOT is defined both by CONFIG_USB_FUNCTION_FASTBOOT AND CONFIG_CMD_FASTBOOT, so it doesn't
make much sense to have a CONFIG_USB_FASTBOOT prefix for fastboot-specific options, especially
given that other config options for fastboot use the CONFIG_FASTBOOT prefix.
This replaces the CONFIG_USB_FASTBOOT prefix with CONFIG_FASTBOOT, for consistency.

Recent versions of the fastboot tool will query the partition type before doing
an operation on a partition (such as erase, flash, etc). It will then submit
the operation as soon as the response for the partition type is received.
Usually, the MUSB controller will see that the partition type request return
status was read by the host at the very same time as the actual operation
request is submitted by the host. However, the operation will be read first
(int_rx is handled first in musb_interrupt) and after it is completed, the
fastboot USB gadget driver will send another return status. Hence, this happens
before the musb gadget framework has had a chance to handle the previous
acknowledgement that the host read the return status and dequeue the request.
The host will then usually empty the FIFO by the time musb_interrupt gets around
handling the return status acknowledgement (for the previous request, this is
still on the same musb_interrupt call), so no other interrupt is generated and
the most recent return status acknowledgement remains unaccounted for.
It will then be used as a response for the next command, and the proper response
for it will be delayed to the next command, and so on.
Dequeuing the previous IN request in the fastboot code ensures that no previous
return status remains. It is acceptable to do it since there is no callback to
it anyways.

This avoids handling requests that have an error status or no data.
In particular, this avoids showing unnecessary error messages when the USB
gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB
gadget driver sends an error back to the host (that has disconnected already).

Weak versions of board_usb_init and board_usb_cleanup are defined in common USB
host code, but it is also used for USB device gadgets, so we also need a weak
definition of it when there is no USB host enabled.
Both weak definitions do not conflict.

Some controllers support OTG (on-the-go) where they can operate as either
host or device. The gadget layer in U-Boot supports this.
While this layer does not interact with driver model, we can provide a
function which sets up the controller in the correct way. This way the code
at least builds (although it likely will not work).

The "fastboot reboot-bootloader" command is defined to
re-enter into fastboot mode after rebooting into
bootloader. This command is usually used after updating
bootloader via fastboot.
This commit implements only a generic side of the
command - setting of the reset flag and then resetting.
Setting of the reset flag is implemented using __weak
fb_set_reboot_flag() function. The actual setting and
checking of the reset flag should be implemented by
a boot script and/or board/SoC specific code.

usb_gadget_handle_interrutps should take controller index as an

controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.
