arm, at91, spl: add spl support for the taurus board
replaces the at91bootstrap code with SPL code.
make the spl image with:
./tools/mkimage -T atmelimage -d spl/u-boot-spl.bin spl/boot.bin
this writes the length of the spl image into the 6th
execption vector. This is needed from the ROM bootloader.
