[PATCH 00/18] Barebox Deep-Probe

[Marco Felsch]

Hi all,

this series is our approach to address the EPROBE_DEFER and initcall
shifting problem. I skip the deep-probe explanation here and instead
refer to the detailed commit message of patch 15. 

Patche 1-11:
 - Fixes and cleanups I found during the development of deep-probe

Patch 12-14:
 - Preliminary for the deep-probe mechanism

Patch 15:
 - The interesting part of this series. This patch implements the
   deep-probe mechanism and adds helpers to make your board deep-probe
   aware.

Patch 16-17:
 - Adds STM32MP1 and i.MX architecture specific deep-probe code. For
   those architectures this means that we need to populate the
   memory-controller.

Patch 18:
 - Convert the sabrelite board to use the deep_probe mechanism. This can
   be used as example for others :)

Comments & testers are welcome :)

PS:
This series is based on Sascha's commit
http://lists.infradead.org/pipermail/barebox/2020-September/033979.html.
You need to apply this one before applying this series.

Regards,
  Marco
