The Buildroot makefile was fetching and building the special AT91Bootstrap of Ulf, which is not the Atmel official version. While Ulf's variant has a better configuration/build system, the Atmel version, as officially supported, is probably a better choice for the future. The Atmel version only needed a small tweak to work with EABI toolchains. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
