Hi Samsung/MTK/Any other SOC vendors,

This is to bring to your notice that, we (Qualcomm) are working on
upstreaming our minidump solution which is to address the problem of
debugging on field device crashes where collecting entire ddr dump
would not be feasible and collecting minimal data from the ddr would
help in debug direction or even help in root causing issue.

We have recently posted v4 version here [1]

Based on comments[2], community is more worried about, if each SOC
vendor come up with their own dumping method today or in future and
whether it can have a common solution to a similar problem faced by
other SOC vendor.

We wanted to take your feedback if you also encounter a similar problem
or maintain something similar solution in downstream which can be
upstreamed. This will help us in a way to have a common solution in
upstream.

Adding the main ARM list to solicit feedback from other silicon
manufacturers.

The cover sheet on the v4 patch set is available at:

I doubt anyone follows the lists, so at least Cc some maintainers.

+Cc Alim, Kukjin, Vignesh, Nishanth, Matthias.

Thanks @Krzysztof/@Brian for extending the list.
