This series merges the fastboot UDP support from AOSP into mainline
U-Boot.

Changes in UDP behaviour from the AOSP code, so it follows the existing USB
behaviour:

- 'boot' now follows the USB code and does 'bootm CONFIG_FASTBOOT_BUF_ADDR'.
  I've added 'fastboot_bootcmd' which if set overrides the boot command and
  allows the existing UDP behaviour to be preserved.
- 'continue' in UDP now exits the fastboot server rather than executing
  'run bootcmd'
- 'reboot-bootloader' no longer writes 'reboot-bootloader' to
  CONFIG_FASTBOOT_BUF_ADDR as its marker for the subsequent boot. The code
  which is in AOSP common/android_bootloader.c expects this marker, but
  we have prior art in the USB code using the weak function
  fastboot_set_reboot_flag
- 'getvar' in the UDP path now supports fetching 'fastboot.' prefixed
  variables (inherited from the USB path), these override the defaults

I've pushed both USB and UDP into a single consolidated protocol layer
now I've tested it on a BeagleBone Green.

Green Travis build: https://travis-ci.org/akiernan/u-boot/builds/381854592

Changes in v6:
- accomodate master change and switch dependency on imx6dl_mamoj from
  FASTBOOT to USB_FUNCTION_FASTBOOT
- delete redundant FASTBOOT_FLASH_NAND_DEV symbol
- add docbook comments
- add docbook comments
- rename fastboot_download_data() to fastboot_data_download(), rename
  fastboot_get_bytes_remaining() to fastboot_data_remaining()
- split fastboot_data_complete() out from fastboot_data_download() so we
  can call it at the end of the transfer phase for USB
- merged from RFC USB fastboot series
- when entering the DATA phase ensure we actually install the correct handler
- on completion of DATA call new fastboot_data_complete()
- previous changes:
  - remove redundant version.h
  - use new fastboot_get_bytes_remaining() function
- new

Changes in v5:
- don't depend on UDP_FUNCTION_FASTBOOT until it exists
- squash in subsequent patch which updates defconfigs so we don't leave users
  of CONFIG_FASTBOOT without it enabled
- fix build in drivers/fastboot when we have CONFIG_FASTBOOT without flash
  or erase and we've not yet added fb_common.c to the build
- fix docbook formatting
- new
- new
- rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE
  and migrate it to Kconfig.
- make fastboot_bytes_received/expected static and add function
  fastboot_get_bytes_remaining()
- move fastboot_buf_addr/fastboot_buf_size/fastboot_progress_callback
  into fastboot-internal.h
- delete redundant fb_ prefixes from statics
- new

Changes in v4:
- add docbook comments
- leave strcmp_l1() in USB fastboot as we don't need it in UDP path
- add docbook comments
- new
- guard fb_getvar/fb_command with UDP_FUNCTION_FASTBOOT in Makefile
- add docbook comments
- remove parameter from fastboot_boot() since we always want
  fastboot_buf_addr (and if we're using fastboot_bootcmd then it's
  ignored)
- split oem format into new patch

Changes in v3:
- move imply ANDROID_BOOT_IMAGE, CMD_FASTBOOT to FASTBOOT from
  USB_FUNCTION_FASTBOOT
- add depend on USB_FUNCTION_FASTBOOT to FASTBOOT_USB_DEV
- leave images-sparse.c in common to acommodate 2f83f21
- refactor for changes in master
- Merge subsequent patch for formatting response strings into this one
- allow NULL to fastboot_okay() when there's no message to send
- guard FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME with EFI/DOS_PARTITION
- new
- new
- new
- new
- new
- new
- use FASTBOOT as our guard in Kconfig not a list of USB || UDP
- correct mis-translation from AOSP introduced when cleaning up for
  checkpatch - we should write when buffer is not NULL, rather than
  erasing, and erase when buffer is NULL
- use CMD_RET_USAGE from do_fastboot
- remove do_fastboot_udp from cmd/net.c and rewrite using net_loop()
- rename timed_send_info to fastboot_send_info, rename fastboot_send_info to
  fastboot_udp_send_info
- replace FASTBOOT_HEADER_SIZE with sizeof(struct fastboot_header)
- move start time into timed_send_info() rather than passing it in
- make calls to fastboot_udp_send_info a runtime dependency, not a compile
  time one
- set ${filesize} to size of downloaded image
- add progress meter from USB path during download
- add support for 'oem format' command from the USB path
- rename 'fastbootcmd' to 'fastboot_bootcmd' to make clear that this is the
  fastboot boot command
- make getvar implementation table driven
- add fastboot_buf_addr, fastboot_buf_size to override buffer address and
  size
- return correct filesystem type in getvar partition-type on MMC
- process "fastboot." prefixed env variables in getvar first so you
  can override the normal values (this also lets you set a fs type for
  NAND devices)
- squash subsequent patches which change this code into this one:
  - If the fastboot flash/erase commands are disabled, remove that support
    so we still build correctly.
  - Add NAND support to fastboot UDP flash/erase commands
  - If we don't have a partition name passed, report it as not found.
  - Change the behaviour of the fastboot net code such that
    "reboot-bootloader" is no longer written to CONFIG_FASTBOOT_BUF_ADDR for
    use as a marker on reboot (the AOSP code in common/android-bootloader.c
    uses this marker - this code could be reinstated there if that gets
    merged).
  - Merge USB and UDP boot code. The USB implementation stays the same, but
    UDP no longer passes an fdt. We introduce a new environment variable
    'fastboot_bootcmd' which if set overrides the hardcoded boot command,
    setting this then allows the UDP implementation to remain the same. If
    after running 'fastboot_bootcmd' the board has not booted, control is
    returned to U-Boot and the fastboot process ends.
  - Separate the fastboot protocol handling from the fastboot UDP code in
    preparation for reusing it in the USB code.

Changes in v2:
- ensure fastboot syntax is backward compatible - 'fastboot 0' means
  'fastboot usb 0'

Separate CMD_FASTBOOT from FASTBOOT and move code and configuration to
drivers/fastboot.

Switch dependencies on FASTBOOT to USB_FUNCTION_FASTBOOT as anyone who wants
FASTBOOT before this series wants USB_FUNCTION_FASTBOOT. Split
USB_FUNCTION_FASTBOOT from FASTBOOT so they retain their existing
behaviour.

Changes in v6:
- accomodate master change and switch dependency on imx6dl_mamoj from
  FASTBOOT to USB_FUNCTION_FASTBOOT

Changes in v5:
- don't depend on UDP_FUNCTION_FASTBOOT until it exists
- squash in subsequent patch which updates defconfigs so we don't leave users
  of CONFIG_FASTBOOT without it enabled
- fix build in drivers/fastboot when we have CONFIG_FASTBOOT without flash
  or erase and we've not yet added fb_common.c to the build

Changes in v4: None
Changes in v3:
- move imply ANDROID_BOOT_IMAGE, CMD_FASTBOOT to FASTBOOT from
  USB_FUNCTION_FASTBOOT
- add depend on USB_FUNCTION_FASTBOOT to FASTBOOT_USB_DEV
- leave images-sparse.c in common to acommodate 2f83f21

* [U-Boot] [PATCH v6 02/18] fastboot: Refactor fastboot_okay/fail to take response
  2018-05-22  9:23 [U-Boot] [PATCH v6 00/18] Add fastboot UDP support Alex Kiernan
  2018-05-22  9:23 ` [U-Boot] [PATCH v6 01/18] fastboot: Move fastboot to drivers/fastboot Alex Kiernan

  2018-05-22  9:23 ` [U-Boot] [PATCH v6 03/18] fastboot: Extract fastboot_okay/fail to fb_common.c Alex Kiernan
                   ` (15 subsequent siblings)
  17 siblings, 0 replies; 26+ messages in thread
From: Alex Kiernan @ 2018-05-22  9:23 UTC (permalink / raw)
  To: u-boot

Add the response string as a parameter to fastboot_okay/fail, instead
of modifying a global, to match the contract expected by the AOSP
U-Boot code.

Add drivers/fastboot/fb_common.c, where fastboot_okay/fail are implemented
so we can call them from a non-USB implementation.

Introduce fastboot_response which takes varargs parameters so we can
use it to generate formatted response strings. Refactor fastboot_okay/fail
to use it.

Ensure that when selecting FASTBOOT_FLASH you end up with a buildable
configuration. Prior to this you could select NAND without MTDPARTS
and end up with an image which (surprisingly) excluded NAND.

Also fix dependencies on FASTBOOT_GPT_NAME/FASTBOOT_MBR_NAME which require
you have EFI_PARTITION/DOS_PARTITION enabled.

Delete redundant FASTBOOT_FLASH_NAND_DEV from Kconfig - it was only ever
used as a guard and the value was ignored in all cases, we're using
FASTBOOT_FLASH_NAND as the guard now.

CONFIG_FASTBOOT_GPT_NAME and CONFIG_FASTBOOT_MBR_NAME are always defined
by Kconfig if you're compiling this code, so remove these redundant
defaults.

Rename fb_set_reboot_flag to fastboot_set_reboot_flag so it matches
all other fastboot code in the global name space. Fix the guards around
them so that they're dependent on FASTBOOT, not just USB_FUNCTION_FASTBOOT.

Move the weak implementation of fastboot_set_reboot_flag to fb_common.c
so we can call it from non-USB fastboot code.

Move FASTBOOT_VERSION to include/fastboot.h so when we merge the UDP code
we only have one definition.

Overriding fastboot_set_reboot_flag() in arch/arm/mach-omap2/boot-common.c
leaves it applying all boards that derive from this, not just the ones which
have support for Android bootloader flow. Move the weak function override to
the relevant board files.

Introduce CONFIG_IMAGE_SPARSE and CONFIG_CMD_MMC_SWRITE so the "mmc
swrite" command is separated from the fastboot code.

Move image-sparse from common to lib so it's clear it's library code.

Rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE
and migrate it to Kconfig.

Changes in v6:
- add docbook comments
- rename fastboot_download_data() to fastboot_data_download(), rename
  fastboot_get_bytes_remaining() to fastboot_data_remaining()
- split fastboot_data_complete() out from fastboot_data_download() so we
  can call it at the end of the transfer phase for USB

Changes in v5:
- make fastboot_bytes_received/expected static and add function
  fastboot_get_bytes_remaining()
- move fastboot_buf_addr/fastboot_buf_size/fastboot_progress_callback
  into fastboot-internal.h
- delete redundant fb_ prefixes from statics

Changes in v4:
- guard fb_getvar/fb_command with UDP_FUNCTION_FASTBOOT in Makefile
- add docbook comments
- remove parameter from fastboot_boot() since we always want
  fastboot_buf_addr (and if we're using fastboot_bootcmd then it's
  ignored)
- split oem format into new patch

Changes in v3:
- use FASTBOOT as our guard in Kconfig not a list of USB || UDP
- correct mis-translation from AOSP introduced when cleaning up for
  checkpatch - we should write when buffer is not NULL, rather than
  erasing, and erase when buffer is NULL
- use CMD_RET_USAGE from do_fastboot
- remove do_fastboot_udp from cmd/net.c and rewrite using net_loop()
- rename timed_send_info to fastboot_send_info, rename fastboot_send_info to
  fastboot_udp_send_info
- replace FASTBOOT_HEADER_SIZE with sizeof(struct fastboot_header)
- move start time into timed_send_info() rather than passing it in
- make calls to fastboot_udp_send_info a runtime dependency, not a compile
  time one
- set ${filesize} to size of downloaded image
- add progress meter from USB path during download
- add support for 'oem format' command from the USB path
- rename 'fastbootcmd' to 'fastboot_bootcmd' to make clear that this is the
  fastboot boot command
- make getvar implementation table driven
- add fastboot_buf_addr, fastboot_buf_size to override buffer address and
  size
- return correct filesystem type in getvar partition-type on MMC
- process "fastboot." prefixed env variables in getvar first so you
  can override the normal values (this also lets you set a fs type for
  NAND devices)
- squash subsequent patches which change this code into this one:
  - If the fastboot flash/erase commands are disabled, remove that support
    so we still build correctly.
  - Add NAND support to fastboot UDP flash/erase commands
  - If we don't have a partition name passed, report it as not found.
  - Change the behaviour of the fastboot net code such that
    "reboot-bootloader" is no longer written to CONFIG_FASTBOOT_BUF_ADDR for
    use as a marker on reboot (the AOSP code in common/android-bootloader.c
    uses this marker - this code could be reinstated there if that gets
    merged).
  - Merge USB and UDP boot code. The USB implementation stays the same, but
    UDP no longer passes an fdt. We introduce a new environment variable
    'fastboot_bootcmd' which if set overrides the hardcoded boot command,
    setting this then allows the UDP implementation to remain the same. If
    after running 'fastboot_bootcmd' the board has not booted, control is
    returned to U-Boot and the fastboot process ends.
  - Separate the fastboot protocol handling from the fastboot UDP code in
    preparation for reusing it in the USB code.

Changes in v2:
- ensure fastboot syntax is backward compatible - 'fastboot 0' means
  'fastboot usb 0'

Convert USB fastboot code to use shared fastboot protocol.

Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com>
---

Changes in v6:
- merged from RFC USB fastboot series
- when entering the DATA phase ensure we actually install the correct handler
- on completion of DATA call new fastboot_data_complete()
- previous changes:
  - remove redundant version.h
  - use new fastboot_get_bytes_remaining() function

Changes in v5: None
Changes in v4: None
Changes in v3: None
Changes in v2: None

+================
 Android Fastboot
-~~~~~~~~~~~~~~~~
+================
 
 Overview
 ========
-The protocol that is used over USB is described in
-README.android-fastboot-protocol in same directory.
 
-The current implementation is a minimal support of the erase command,the
-"oem format" command and flash command;it only supports eMMC devices.
+The protocol that is used over USB and UDP is described in the
+``README.android-fastboot-protocol`` file in the same directory.
+
+The current implementation supports the following standard commands:
+
+- ``boot``
+- ``continue``
+- ``download``
+- ``erase`` (if enabled)
+- ``flash`` (if enabled)
+- ``getvar``
+- ``reboot``
+- ``reboot-bootloader``
+- ``set_active`` (only a stub implementation which always succeeds)
+
+The following OEM commands are supported (if enabled):
+
+- oem format - this executes ``gpt write mmc %x $partitions``
+
+Support for both eMMC and NAND devices is included.
 
 Client installation
 ===================
-The counterpart to this gadget is the fastboot client which can
-be found in Android's platform/system/core repository in the fastboot
-folder. It runs on Windows, Linux and even OSX. Linux user are lucky since
-they only need libusb.
-Windows users need to bring some time until they have Android SDK (currently
-http://dl.google.com/android/installer_r12-windows.exe) installed. You
-need to install ADB package which contains the required glue libraries for
-accessing USB. Also you need "Google USB driver package" and "SDK platform
-tools". Once installed the usb driver is placed in your SDK folder under
-extras\google\usb_driver. The android_winusb.inf needs a line like
-
-   %SingleBootLoaderInterface% = USB_Install, USB\VID_0451&PID_D022
-
-either in the [Google.NTx86] section for 32bit Windows or [Google.NTamd64]
-for 64bit Windows. VID and PID should match whatever the fastboot is
-advertising.
+
+The counterpart to this is the fastboot client which can be found in
+Android's ``platform/system/core`` repository in the fastboot
+folder. It runs on Windows, Linux and OSX. The fastboot client is
+part of the Android SDK Platform-Tools and can be downloaded from:
+
+https://developer.android.com/studio/releases/platform-tools
 
 Board specific
 ==============
+
+USB configuration
+-----------------
+
 The fastboot gadget relies on the USB download gadget, so the following
 options must be configured:
 
-CONFIG_USB_GADGET_DOWNLOAD
-CONFIG_USB_GADGET_VENDOR_NUM
-CONFIG_USB_GADGET_PRODUCT_NUM
-CONFIG_USB_GADGET_MANUFACTURER
+::
+
+   CONFIG_USB_GADGET_DOWNLOAD
+   CONFIG_USB_GADGET_VENDOR_NUM
+   CONFIG_USB_GADGET_PRODUCT_NUM
+   CONFIG_USB_GADGET_MANUFACTURER
 
-NOTE: The CONFIG_USB_GADGET_VENDOR_NUM must be one of the numbers supported by
-the fastboot client. The list of vendor IDs supported can be found in the
-fastboot client source code (fastboot.c) mentioned above.
+NOTE: The ``CONFIG_USB_GADGET_VENDOR_NUM`` must be one of the numbers
+supported by the fastboot client. The list of vendor IDs supported can
+be found in the fastboot client source code.
 
-The fastboot function is enabled by defining CONFIG_USB_FUNCTION_FASTBOOT,
-CONFIG_CMD_FASTBOOT and CONFIG_ANDROID_BOOT_IMAGE.
+General configuration
+---------------------
 
-The fastboot protocol requires a large memory buffer for downloads. This
-buffer should be as large as possible for a platform. The location of the
-buffer and size are set with CONFIG_FASTBOOT_BUF_ADDR and
-CONFIG_FASTBOOT_BUF_SIZE.
+The fastboot protocol requires a large memory buffer for
+downloads. This buffer should be as large as possible for a
+platform. The location of the buffer and size are set with
+``CONFIG_FASTBOOT_BUF_ADDR`` and ``CONFIG_FASTBOOT_BUF_SIZE``. These
+may be overridden on the fastboot command line using ``-l`` and
+``-s``.
+
+Fastboot environment variables
+==============================
+
+Partition aliases
+-----------------
 
 Fastboot partition aliases can also be defined for devices where GPT
 limitations prevent user-friendly partition names such as "boot", "system"
 and "cache".  Or, where the actual partition name doesn't match a standard
-partition name used commonly with fastboot.  Current implentation checks
-aliases when accessing partitions by name (flash_write and erase functions).
-To define a partition alias add an environment variable similar to:
-fastboot_partition_alias_<alias partition name>=<actual partition name>
-Example: fastboot_partition_alias_boot=LNX
+partition name used commonly with fastboot.
+
+The current implementation checks aliases when accessing partitions by
+name (flash_write and erase functions).  To define a partition alias
+add an environment variable similar to:
+
+``fastboot_partition_alias_<alias partition name>=<actual partition name>``
+
+for example:
+
+``fastboot_partition_alias_boot=LNX``
+
+Variable overrides
+------------------
+
+Variables retrived through ``getvar`` can be overridden by defining
+environment variables of the form ``fastboot.<variable>``. These are
+looked up first so can be used to override values which would
+otherwise be returned. Using this mechanism you can also return types
+for NAND filesystems, as the fully parameterised variable is looked
+up, e.g.
+
+``fastboot.partition-type:boot=jffs2``
+
+Boot command
+------------
+
+When executing the fastboot ``boot`` command, if ``fastboot_bootcmd`` is set then
+that will be executed in place of ``bootm <CONFIG_FASTBOOT_BUF_ADDR>``.
 
 Partition Names
 ===============
-The Fastboot implementation in U-boot allows to write images into disk
-partitions (currently on eMMC). Target partitions are referred on the host
-computer by their names.
+
+The Fastboot implementation in U-Boot allows to write images into disk
+partitions. Target partitions are referred on the host computer by
+their names.
 
 For GPT/EFI the respective partition name is used.
 
 For MBR the partitions are referred by generic names according to the
 following schema:
 
-  <device type> <device index letter> <partition index>
+  <device type><device index letter><partition index>
 
-Example: hda3, sdb1, usbda1
+Example: ``hda3``, ``sdb1``, ``usbda1``
 
 The device type is as follows:
 
-  * IDE, ATAPI and SATA disks: hd
-  * SCSI disks: sd
-  * USB media: usbd
-  * MMC and SD cards: mmcsd
-  * Disk on chip: docd
-  * other: xx

 Writing Partition Table
 =======================
+
 Fastboot also allows to write the partition table to the media. This can be
 done by writing the respective partition table image to a special target
 "gpt" or "mbr". These names can be customized by defining the following
 configuration options:
 
-CONFIG_FASTBOOT_GPT_NAME
-CONFIG_FASTBOOT_MBR_NAME
+::
+
+   CONFIG_FASTBOOT_GPT_NAME
+   CONFIG_FASTBOOT_MBR_NAME
 
 In Action
 =========
-Enter into fastboot by executing the fastboot command in u-boot and you
-should see:
-|GADGET DRIVER: usb_dnl_fastboot
+
+Enter into fastboot by executing the fastboot command in U-Boot for either USB:
+
+::
+
+   => fastboot usb 0
+
+or UDP:
+
+::
+
+   => fastboot udp
+   link up on port 0, speed 100, full duplex
+   Using ethernet at 4a100000 device
+   Listening for fastboot command on 192.168.0.102
 
 On the client side you can fetch the bootloader version for instance:
-|>fastboot getvar bootloader-version
-|bootloader-version: U-Boot 2014.04-00005-gd24cabc
-|finished. total time: 0.000s
+
+::
+
+   $ fastboot getvar bootloader-version
+   bootloader-version: U-Boot 2014.04-00005-gd24cabc
+   finished. total time: 0.000s
 
 or initiate a reboot:
-|>fastboot reboot
+
+::
+
+   $ fastboot reboot
 
 and once the client comes back, the board should reset.
 
 You can also specify a kernel image to boot. You have to either specify
-the an image in Android format _or_ pass a binary kernel and let the
+the an image in Android format *or* pass a binary kernel and let the
 fastboot client wrap the Android suite around it. On OMAP for instance you
 take zImage kernel and pass it to the fastboot client:
 
-|>fastboot -b 0x80000000 -c "console=ttyO2 earlyprintk root=/dev/ram0
-|	mem=128M" boot zImage

Hi Alex,

I tested this new patch series (v6) on X15 board, and this patch still
breaks "fastboot oem format". I see next messages.

On host:

    FAILED (remote: unrecognized command)

On device:

    command oem format not recognized.

All other fastboot commands seem to work fine, though. Can you please
look into it? I can help you with testing on my boards, if you are
unable to reproduce it. You can prepare GitHub branch for debugging
and ask me to check that, I will send you the output.

Thanks.

Btw, I looked in my .config, and I see that:

    # CONFIG_FASTBOOT_CMD_OEM_FORMAT is not set

What I think should be done, is in your patch:

    fastboot: Add support for 'oem format' command

make default=y for FASTBOOT_CMD_OEM_FORMAT. Or add that to all boards
that use "fastboot oem format". Not sure what is proper way here, but
defaulting it to "n" (like it's done now) might break a lot of boards.

Oh bother... and thank you for testing (again).

I guess if we enable it on all boards that currently select USB fastboot as
part of the patch that merges USB and UDP, then we'll get all existing
boards and don't end up with a default y?

As I see it, the only correct approach in this case is to keep it as
it was before. So basically all configs that defined
FASTBOOT_FLASH_MMC_DEV option (explicitly or implicitly), should also
have FASTBOOT_CMD_OEM_FORMAT enabled.

Yeah, that's more or less what I've done... I've added it to boards that
match FASTBOOT_FLASH_MMC_DEV && CMD_GPT (since that's what the
implementation uses) - there's 37 of them. There's another 7 that have
FASTBOOT_FLASH_MMC_DEV but don't have CMD_GPT.

Just posted a version which includes these changes (in fact it's the only
change from v6).

It's also here - https://github.com/akiernan/u-boot/tree/us-fastboot-udp-v7
