Not completely true,
For the AT91RM9200, the dataflashboot was built for ARM ADS
and the same for boot.bin/loader.bin used to handle parallel flash
memories.

Someone ported dataflashboot.bin to gcc and put it on the www.at91.com
and I have used that for my "dataflashboot-1.05.bin" which compiles by gcc.

For the AT91SAM926xEK you use at91-bootstrap and it is recommended that
you compile this by a gcc using newlib from www.gnuarm.com.

Since I am using buildroot, I want everything to compile using uclibc,
NWFPE and a dynamic C library.
softfloat is nice, but there are very few gcc compiler versions which
supports it for ARM.
