For boards using the new NAND +approach (PPChameleon and netstar at the moment) no variable is +necessary, but the config.mk should have "BOARDLIBS = +drivers/nand/libnand.a". + +The necessary changes have been made to all affected boards, and no +build breakage has been introduced, except for NETTA and NETTA_ISDN +targets from MAKEALL. This is due to the fact that these two boards +use JFFS, which has been adopted to use the new NAND, and at the same +time use NAND in legacy mode.
