| | | | | | | | | | | | | | | | | | | | | | | | | | | | First of all U-Boot is not that performance oriented as real run-time software like OS or user bare-metal app so we may afford being not super fast as we only being executed once.

| | | | | | | | | | | | | | | | | | | | | | | | | | It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.
