Subject: [PATCH v2 0/8] Barebox Deep-Probe
Date: Wed, 30 Sep 2020 10:47:08 +0200 [thread overview]
Message-ID: <20200930084716.4200-1-m.felsch@pengutronix.de> (raw)
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 5.
Thanks a lot to Sascha and Ahmad for the review feedback :) Each patch
has a own changelog so I dropped it from the cover letter.
Patch 1:
- Another fixes patch. In V1 this was part of patch 5. I seperate this
patch to make it more clear and clean.
Patche 2-4
- Deep probe preparation patche
Patch 5:
- The interesting part of this series. This patch implements the
deep-probe mechanism and adds helpers to make your board deep-probe
aware.
Patch 6-7:
- Adds STM32MP1 and i.MX architecture specific deep-probe code. For
those architectures this means that we need to populate the
memory-controller.
Patch 8:
- Convert the sabrelite board to use the deep_probe mechanism. This can
be used as example for others :)
Comments and testers are welcome, as always :)
Regards,
Marco
