when i compiled u-boot 1.1.5 for atmel's at91sam9261-ek...initially it gave
the error as -maps-32 not found...which is in config c file in the
cpu/arm926ejs/at91sam9261x directory of the source code provided from
timesys...
but when i deleted this string in the file and recompiled it, generated the
bin file..
to my surprise it was 1kb less than original bin file...
one more modification wt i made was in the makefile..
here i changed arch CROSS_COMPILE=arm-softfloat-linux-
to armv5l-linux- because my toolchain has armv5l-linux-gcc....

but when i ported the bin file...board is not getting booted...
any reason why it is so...

It's the same reason why your board wouldn't boot if you set
CROSS_COMPILE to a M$ Visual Whatever compiler. ;-) It isn't sufficient
to use an arbitrary compiler which has something to do with ARM and
also understands GNU extensions.

Did you notice the "softfloat" in "arm-softfloat-linux-"?

With best regards
