These were only used as an example and it's trivial to switch to other hash algos or RSA key sizes. Also, the FIT format can easily be extended to support ECC/Curve25519. In some cases, where the SoC's ROM code only supports RSA2048 with SHA1, using stronger settings in Barebox doesn't increase security. So there we want to use the same settings as the ROM code.
