Commit Message

I would like to create a generic U-Boot build that adapts itself completely
based on the DT passed in. That way we can potentially support running
random board configurations with a single U-Boot binary built as part of
the distribution.

Currently a few things are still missing to make it a full reality. The
most obvious one I think is the EEPROM location. This would need to also
move into something described by DT.

Apart from that, we're almost there. This patch adds a defconfig that simply
contains all drivers we could make use of. We can then enable individual
boards along the way and slowly adapt everything to be fully DT described
while we identify each missing bit.

v1 -> v2:

  - Remove debug uart

v2 -> v3

  - show model information instead of custom IDENT_STRING

v3 -> v4:

  - reintroduce CONFIG_IDENT_STRING
  - remove CONFIG_DEFAULT_DEVICE_TREE
  - run through savedefconfig
  - replace CONFIG_SYS_I2C_ZYNQ with CONFIG_SYS_I2C_CADENCE
  - remove CONFIG_ZYNQ_SDHCI{0,1} - needs to be solved generically
  - add xhci usb1 to xhci controller list

I still have the same concern as I have told you here.
https://lists.denx.de/pipermail/u-boot/2018-April/326477.html

It is not that generic as it is suggest to be.
Resolving that issues first is IMHO the best way to go instead of
pretending that we are there by new target.

Thanks,
Michal
