[PATCH u-boot-mvebu 00/10] Turris Omnia DDR training changes

[Marek Behún]

Hi Stefan,

this series adds some changes to DDR3 training for Armada 38x and
Turris Omnia.

- patches 1-4 are meant to allow for reducing another 10 KiB in the
  SPL binary. They were also sent to mv-ddr-marvell, via PR on github,
  https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell/pull/45/
  but I am told that Armada team has left Marvell, so who knows if this
  will ever be merged there
- patch 5 enables this reduction for Turris Omnia
- patches 6-8 import old DDR3 training code and make some changes so
  that it works with U-Boot. The reason why this is being done is
  explained in patch 6
- patch 9 glues the old DDR3 training code to current U-Boot
- patch 10 allows for dynamic selection of old DDR3 training code on
  Turris Omnia, via an U-Boot environment variable
