[U-Boot] Flash Errors in Building u-boot.2009.03 for mx31ads

[Yong Yang]

I ran into a bunch of errors related to Flash and Net (e.g. undefined
reference to 'flash_init'), when building u-boot for mx31ads.

lib_arm/libarm.a(board.o)(.text+0x1d8): In function `start_armboot':
/home/yong/cross-compile/u-boot-2009.03/lib_arm/board.c:211: undefined
reference to `flash_init'
lib_arm/libarm.a(board.o)(.text+0x2c4):/home/yong/cross-compile/u-boot-2009.03/lib_arm/board.c:442:
undefined reference to `cs8900_get_enetaddr'
lib_arm/libarm.a(board.o)(.data+0xc): In function `sbrk':
/home/yong/cross-compile/u-boot-2009.03/lib_arm/board.c:111: undefined
reference to `env_init'
net/libnet.a(net.o)(.text+0x1dc): In function `ArpRequest':
/home/yong/cross-compile/u-boot-2009.03/net/net.c:254: undefined reference

I checked include/configs/mx31ads.h, and it does use CFI flash
configuration. Does anyone have ideas what might go wrong? Thanks
