Re: DTC failure on /memreserve/ if moved after /include/

The following from tegra-harmony.dts compiles fine:

    /dts-v1/;

    /memreserve/ 0x1c000000 0x04000000;
    /include/ "tegra250.dts"

    / {

However, if I re-order this as follows:

    /dts-v1/;
    /include/ "tegra250.dts"

    /memreserve/ 0x1c000000 0x04000000;

    / {

Then dtc fails:

Is this a dtc bug, or does the DTS syntax actually disallow this?

Correct.  The grammar is explicitly:

    sourcefile:
	      DT_V1 ';' memreserves devicetree
	    ;

    memreserves:
	      /* empty */
	    | memreserve memreserves
	    ;

    memreserve:
	      DT_MEMRESERVE addr addr ';'


and then much later devicetree leads to...:


    propdata:
	      propdataprefix DT_STRING
	    | propdataprefix '<' celllist '>'
	    | propdataprefix '[' bytestring ']'
	    | propdataprefix DT_REF
	    | propdataprefix DT_INCBIN '(' DT_STRING ',' addr ',' addr ')'

where INCBIN is the include mechanism.
