Hi Geert,
Thanks for the series. One question below.

It is common practice in Renesas BSP to specify the SiP memory
split by suffixing the DTB names with '-{2,4}x{2,4}g' [1].
Has this ever been discussed on ML?
Here in particular, it would allow M3-W+ 2x4GiB Salvator-XS and
M3-W+ 2x2GiB (or any other DRAM split flavor of) Salvator-XS to
coexist in harmony, if the latter pops up at any point.
