Oh..., sorry, I don't run makeall to test and fell free to revert it,
but not this patch,
 this patch doesn't be included on your git tree, I think you means the
following patch:
http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commit;h=511c02f611
cb5afa1b8ca5980caaaabaa0de377f

Obviously, this patch also causes these issues, so can I parse the board
config name
in the top make file by using the "findstring" method which will make
the top make file
a little lengthy? If yes, I'll resend the patchset for boot from
NAND/eSDHC/eSPI again.

Thanks,
Mingkai
