Subject: Removal of qcom,board-id and qcom,msm-id

Hi,

There was an old effort of removal of qcom,board-id and qcom,msm-id
properties from Qualcomm SoC-based boards like [1].

First approach was to document them, which (obviously) was not well
received [2] [3] [4].

The solution from Stephen was to encode these in the board compatible,
so bootloader can extract that information. That seemed to receive
positive comments, at least from Rob. [5]

It was 2015... ~7 years later we are still things doing the same way,
still with undocumented properties: qcom,board-id and qcom,msm-id.


I would like to revive that topic, but before I start doing something
pointless - any guidance on last patch from Stephen [5]? Was it ok? Some
early NAKs?
