[PATCH 00/19] Slices and fastboot over UDP

[Sascha Hauer <s.hauer@pengutronix.de>]

This is a combination of the slices series I posted earlier and
the fastboot over ethernet series from Daniel Glöckner. This works
quite well for me now and I am impressed that with a small fix both
fastboot over USB and over UDP now not only work after each other,
but also truely simultanously. Well, I didn't try to write the same
file from both instances, that won't work for sure ;)

This series currently has three known issues which should be fixed
before merging:

- The fastboot UDP keepalive handler has no idea if we are inside a
  fastboot session or not. It will just blindly send keepalive packets
- The only possibility to start fastboot over UDP currently is a
  Kconfig option which if enabled starts fastboot over UDP unconditionally
  Here we need at least a nv variable to control starting
- It's not yet clear if completely removing the may_send mechanism is the
  right thing.

Changes since the slices v4 series:

- rename slice_add() to slice_depends_on() which makes the intention of
  the function more clear
- slice_del() is no longer necessary and removed
- slice_exit() introduced to remove a slice. This removes the slice, it's
  dependencies and also removes the slice from other slices dependencies

Changes since fastboot over UDP v2:

- squashed 01/10 - 03/10 into patches of the slices series
- Move releasing of the idle slice to the shell and the startup code
  calling the autoboot timeout counter
- add forgotten rename of global.usbgadget.fastboot_max_download_size to
  global.fastboot.max_download_size
- Add patch to use different temporary filenames for each fastboot instance.
  With this fastboot over UDP and fastboot over USB can work in parallel
- remove may_send mechanism from fastboot over UDP
- fix wrong test in fastboot_net_exit()

Daniel Glöckner (4):
  fastboot: don't close fd 0 when downloading to ram
  Introduce idle slice
  defconfigs: update renamed fastboot options
  fastboot: rename usbgadget.fastboot_* variables to fastboot.*

Edmund Henniges (2):
  fastboot: split generic code from USB gadget
  fastboot net: implement fastboot over UDP

Sascha Hauer (13):
  poller: Give pollers a name
  poller: Add a poller command
  fastboot: Use unique tempfile name
  Introduce slices
  net: Add a slice to struct eth_device
  net: mdiobus: Add slice
  usb: Add a slice to usb host controllers
  usbnet: Add slice
  net: Call net_poll() in a poller
  net: reply to ping requests
  usbnet: Be more friendly in the receive path
  poller: Allow to run pollers inside of pollers
  fastboot net: remove may_send
