it passes a build test on the 8313, but applying the same change to the
8315 still fails to build with bootstrap too big errors, because it
still suffers from the extra bits. At least now it's buildable, so
we have some size info for the curious:
before (fits):
$ size ./nand_spl/board/freescale/mpc8315erdb/start.o
text data bss dec hex filename
1528 12 0 1540 604 ./nand_spl/board/freescale/mpc8315erdb/start.o
after (too big):
$ size ./nand_spl/board/freescale/mpc8315erdb/start.o
text data bss dec hex filename
1588 20 0 1608 648 ./nand_spl/board/freescale/mpc8315erdb/start.o
and there are other 83xx nand boards; please at least MAKEALL 83xx
before resubmitting.
Thanks,
Kim
