Why isn't this padding and alignment with the BSS being taken
care
of
in either the linker script or the binman dts?
Sorry, I am not sure what you mean.
I mean, why are things placed in this position to start with? Why is the device tree not already in a place where we aren't smashing it at run time? Is this a problem of the alignment / placement of items in a blob? A runtime placement problem? What?
Whether binman or not. I think u-boot.dtb is padded just end of u-boot-nodtb.bin. Not alignment or else.
This is a common issue, bss should not be written before reloc_fdt.
