[U-Boot] OMAP3 EVM board nand support missed

[Arno Steffen]

Testing the latest release (2009-08) I missed the NAND support (there
is just ONENAND).
Adding the line in config
#define CONFIG_CMD_NAND		/* NAND support		*/
cause a error in building uboot:
...drivers/mtd/nand/libnand.a(nand.o): In function `nand_init_chip':
/opt/src/ub/u-boot-ti-git-2009-08/drivers/mtd/nand/nand.c:53:
undefined reference to `board_nand_init'
make: *** [u-boot] Fehler 1

Is this intentionally not supported anymore? What's to do to get nand
support for my board?
