No other subsystem generates ANSI characters when U-Boot starts. Why are we creating this problem in the EFI implementation?
So please, I very-much want to have a way to stop this output from being generated, not to filter it afterwards. As above, we should design U-Boot for easy testing, not treat it as a black box. Please do seriously consider this as I believe this is an important testing principle being violated here.
This is, I think, a good point. Outside of user-facing interactive code, we don't use ANSI sequences for printing information in U-Boot anywhere else. Why are we doing it in the EFI_LOADER code outside of personal preference? And, can we just not instead? It does confuse matters (as my example showed) when problems do arise.
