The name appended to tiboot3 is not the board or the soc, it is
the name of the SYSFW (TIFS and DM) used, and in this case since
you are packaging the "am62ax" TIFS/DM, then the name should be
tiboot3-am62ax-hs-evm.bin. With that change this file would be
near identical to k3-am62a-evm-binman.dtsi, so why not just include
that and override the one or two spots that need changed (default
dts file and description being the only thing I can see).
