I could successfully build u-boot 1.1.1 and 1.1.4 for ATMEL at91rm9200
CPU with softfloat option using following Kegel combination:
gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu (linux kernel and root
file systems are also built and working).

However I could run only u-boot 1.1.1 and that only after change:

Basically, I don't put gd into the register - crosstool somehow doesn't
compile it properly (I examined the assembler).
