2918eb9d42 Remove shell variable UNDEF_SYM. 
UNDEF_SYM is a shell variable in the main Makefile used to force the
linker to add all u-boot commands to the final image. It has no use here.

fdd1247a66 ppc4xx: Individual handling of ddr2_fixed.c for canyonlands_nand build 
Canyonlands has a file ddr2_fixed.c which needs special treatment when
building in separate directory. It has to be linked to build directory
otherwise it is not seen.

71665ebf88 ppc4xx: Add Canyonlands NAND booting support 
460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.

This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.

Tested with 512 byte page NAND device (32MByte) on Canyonlands.
