Would it be possible to build a single image for an entire MX6 lineup of CPUs ? I think it is now possible to build a single image for MX6 Quad/Dual/DualLite/Solo ... do SX and UL integrate well into this too? Seeing this patch, I don't think so ...
A single image you mean like linux kernel, one image cover all the arch/driver code, and using dts to cover board part?
Eventually yes, but this can be done without DT too.
If so, agree to build a single image for i.MX6, but dtb is not added now. To kernel, pinmux header are used for dtb, but now we do need this file to set pinmux in uboot board file.
See arch/arm/include/asm/arch-mx6/mx6-pins.h and in particular CONFIG_MX6QDL option. It allows defining pins for both MX6Q and DL (and solo), thus you can build single image for a board which might use all three options. I think it should be possible to add SX and UL into this mix too.
SX and UL have different pinmux from others.
OK

How very different is this from Solo or SoloX ? Is the pinmux map really that different that it needs a new file of it's own (I did not check) ?
SX and UL have different pinmux map.
OK
