e52a250d2381 ("ARM: boards: Harmonize barebox_arm_reset_vector() prototype")
has unified the prototype, so we can drop this TODO item.

[PATCH 2/2] ARM: at91: define new at91_multi_defconfig

[Ahmad Fatoum]

We now have 5 boards supporting multi-image, so add a defconfig that
covers these three boards:
  - Microchip KSZ-9477 EVB
  - Microchip SAMA5D27-SOM1-EK
  - Groboards Giantboard

For the latter two, two images are built. One with only a first stage
PBL and another with a second-stage barebox proper.

Two more at91 multi-image boards are left out:
  - Atmel AT91SAM9263-EK
  - Atmel AT91SAM9x5 Series Evaluation Kit

They have a 256K barebox NAND partition in the device tree, so this
multi-image build would not fit and I don't have the hardware to test
them anyway.

Nice!
My limited hacking time is wasted^Wwused for DRM hacking these dyas so
no time for barebox love :-(

With the updated NAND partitioning I enabled these as well for the
at91_multi_defconfig.
