I don't know toolchain coming with ELDK 4.2, but for U-Boot for OMAP 
35x you don't need a special compiler. A non-broken arm-linux-gcc or 
similar will work. While bringing OMAP U-Boot support to mainline, we 
explicitly switched to a more conservative toolchain configuration 
(-march=armv5 instead of v7a) to enable more toolchains to work.

Try the toolchain you have and ask or report errors if it doesn't work.

Best regards

Dirk

Btw.: For other code, e.g. Linux user space programs which need 
special optimizations, other toolchain might be necessary, though.
