u-boot/board/stxxtc/stxxtc.c
Bartlomiej Sieka addb2e1650 Re-factoring the legacy NAND code (legacy NAND now only in board-specific 
code and in SoC code). Boards using the old way have CFG_NAND_LEGACY and
BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.
