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'll post the USB migration as a separate 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
- move Kconfig changes to previous patch
- 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
- 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'

* [U-Boot] [PATCH v3 03/13] fastboot: Refactor fastboot_okay/fail to take response

From: Alex Kiernan @ 2018-05-14  9:08 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.

  To: u-boot

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.

Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>

Changes in v3:
- Merge subsequent patch for formatting response strings into this one
- allow NULL to fastboot_okay() when there's no message to send

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.

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 strcmp_l1() to include/common.h so we can can call it from elsewhere.
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.

Add fs_get_type_name so we can get the current filesystem type.

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'

When I was looking through the size changes, I realised that by the time I
was done I'd removed this completely, so I'll just drop it altogether.

Will do... I don't think I can easily make the remaining globals go away,
but I can certainly put them behind accessor functions.

If you can't make them go away, or put them in a struct, then I don't
think you should bother with accessor function, which just mess up the
code IMO.

So it was a worthwhile exercise to go through it again... I got two more of
the globals into statics (and a function to return the amount of data we
still expect to transfer), which left the buffer address, buffer size, and
the progress callback to keep the protocol alive, all of which are only
used inside drivers/fastboot itself, which I'll move to a
fastboot-internal.h
