07:58 <austriancoder> I need to support the following SoCs: AM6411, AM6421 and AM6442. I want to only have *one* U-Boot for all of these. AFAICT only the A53/R5F core count is different between these models. Is there anything I might be missing?

13:31 <NishanthMenon> austriancoder: you should be fine.. min config you seem to have is 1 boot r5 and 1 a53... in the boot flow, until linux startsup, we dont do anything to additional CPUs.. u-boot does'nt use additional resources.. TF-A will invoke additional A53 core depending on kernel dts (the reason also why we split up am642.dtsi)

13:48 <austriancoder> NishanthMenon: ahh yes.. U-Boot does not need the additional CPUs.. great

13:50 <NishanthMenon> austriancoder: just be sure to have the right kernel dts... also with FIT image load, you should technically be able to detect the board rev (if you have such capability) and load variations.. I am going to guess (low core count == low cost == lower BoM), you probably have variant sizes of DDR as possible..

13:54 <austriancoder> NishanthMenon: correct. we are playing with a device tree overlay for the ddrss settings that gets loaded in spl ..

13:54 <austriancoder> NishanthMenon: so I think/hope everything should be fine

13:58 <NishanthMenon> austriancoder: ok cool.. fun combi you have there ;)

14:22 <NishanthMenon> just reference https://www.ti.com/lit/ds/symlink/am6442.pdf -> Table 5-1. Device Comparison (page 8)

15:07 <austriancoder> thx
