Hi,
I have created a new PR:
https://github.com/openwrt/openwrt/pull/5074
Which also includes a remote processor framework kernel module, which
has not been sent upstream yet. But it could be the basis to make wifi
or the secondary SoC work too.
It still misses a way of configuring the wifi part, but that can be scripted and
will neither added nor covered by this PR, because its a separate topic and
likely belongs to a feeds package.
Looking at your submitted patches, many fritzbox devices have different
NAND manufacturers. So the best way is to support all.
I created a DTB and image configuration for Micron and non Micron NAND.
This is probably the best way and not supporting just one NAND type per
device. Unfortunately auto detection was not accepted by the kernel
maintainers, so there is no other solution.
I also saw the addition of ubifs. I have not used this so far and I wonder
what the advantage is over using squashfs with overlay?
Let me cite https://en.wikipedia.org/wiki/UBIFS
- tracking NAND flash bad blocks
- providing wear leveling
NAND is a rather unreliable type of flash, hence some special treatment
has to be done to make it last as long as possible.
