da83ada02a usb: gadget: Add and use matching SPL USB ethernet gadget Kconfig symbols
Define SPL_USB_ETH_RNDIS symbol to make it possible to select USB
gadget ethernet support in SPL and U-Boot separately in Kconfig .
Make use of the new symbols in gadget Makefile and move the rndis.o
just below the now merged USB_ETHER symbol in Makefile.

0007fb2ff7 usb: Move SPL_USB_GADGET and related Kconfig symbols to drivers/usb/
To avoid piling up all the various Kconfig symbols in one place, i.e.
common/spl/Kconfig, move the USB Kconfig symbols into drivers/usb/ .
This commit moves SPL_USB_GADGET and related symbols. Fix typo and

Update the gadget Makefile to match the symbol changes.

The spl_board_prepare_for_boot() should be called before jump_to_image_no_args()

6e7df1d151 global: Finish CONFIG -> CFG migration
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

30f3333d88 image: Move common image code to image_board and command
We should use the cmd/ directory for commands rather than for common code
used elsewhere in U-Boot. Move the common 'source' code into

The image_source_script() function needs to call run_command_list()  so

2383e8f4ae usb: gadget: dwc2_udc_otg: implement pullup()
Pullup is used by the usb framework in order to do software-controlled
usb_gadget_connect() and usb_gadget_disconnect().

Implement pullup() for dwc2 using the SOFT_DISCONNECT bit in the dctl
register:
* when pullup is on, clear SOFT_DISCONNECT
* when pullup is off, set SOFT_DISCONNECT

This is especially useful when a gadget disconnection is initiated but
no board_usb_cleanup() is called.

The "fastboot reboot" command detaches the USB when it still needs to be

bcc85b96b5 cmd: source: Support specifying config name
As discussed previously [1,2], the source command is not safe to use with
verified boot unless there is a key with required = "images" (which has its
own problems). This is because if such a key is absent, signatures are
verified but not required. It is assumed that configuration nodes will
provide the signature. Because the source command does not use
configurations to determine the image to source, effectively no
verification takes place.

To address this, allow specifying configuration nodes. We use the same
syntax as the bootm command (helpfully provided for us by fit_parse_conf).
By default, we first try the default config and then the default image. To
force using a config, # must be present in the command (e.g. `source
$loadaddr#my-conf`). For convenience, the config may be omitted, just like
the address may be (e.g. `source \#`). This also works for images
(`source :` behaves exactly like `source` currently does).

51a0e215ec usb: gadget: rndis: Prevent InformationBufferOffset manipulation
Prevent access to arbitrary memory locations in gen_ndis_set_resp
via manipulation of buf->InformationBufferOffset. Original
implementation permits manipulation of InformationBufferOffset to
exploit OID_GEN_CURRENT_PACKET_FILTER to set arbitrary memory contents
within a 32byte offset as the devices packet filter. The packet filter
value may be next retrieved using gen_ndis_query_resp so it is possible
to extract specific memory regions two bytes a time.

The rndis_query_response was not modified as neither the buffer offset
nor length passed to gen_ndis_query_resp is used.

5f7e01e9d5 usb: gadget: fastboot: detach usb on reboot commands
When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.

On some boards, such as Khadas VIM3L and SEI610, this is not the case.

We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot                            OKAY [  0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.

This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
  # echo b > /proc/sysrq-trigger

In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.

Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.

Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).

  the Next State is dfuIDLE

In current code, when an UPLOAD is completely performed after the first
request (for example with wLength=200 and data read = 9), the DFU state
stay at dfuUPLOADIDLE until receiving a DFU_UPLOAD or a DFU_ABORT request
even it is unnecessary as the previous DFU_UPLOAD request already reached
the EOF.

This patch proposes to finish the DFU uploading (don't go to dfuUPLOADIDLE)
and completes the control-read operation (go to DFU_STATE_dfuIDLE) when
the first UPLOAD response has a short frame as an end of file (EOF)
indicator even if it is not explicitly allowed in the DFU specification
but this seems logical.

fc2b399ac0 usb: gadget: Add CDC ACM function
Add support for CDC ACM using the new UDC and gadget API. This protocol
can be used for serial over USB data transfer and is widely supported
by various OS (GNU/Linux, MS-Windows, OSX...). The usual purpose of
such link is to access device debug console and can be useful for
products not exposing regular UART to the user.

A default stdio device named 'usbacm' is created, and can be used
to redirect console to USB link over CDC ACM:

> setenv stdin usbacm; setenv stdout usbacm

2e0429bcc1 SPL: Add struct spl_boot_device parameter into spl_parse_board_header()
Add parameter spl_boot_device to spl_parse_board_header(), which allows
the implementations to see from which device we are booting and do
boot-device-specific checks of the image header.

8f758683a8 usb: gadget: dwc2_udc_otg: set ep's desc during enable/disable
Fastboot support has been broken on platforms using dwc2 controller
since the gadget gets its max packet size from it.
This patch is the equivalent of 723fd5668f which fixed the same issue
but for the chipidea controller.

Fixes: 27c9141b11 ("usb: gadget: fastboot: use correct max packet size")
