Yes that's right. It makes it clear what needs changing.

Yes, we need to be careful when calling something legacy or not. init.h also sounds like a good place in this case, thanks! -- Tom ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

As far as I understand from your patch series, you're mainly using _legacy to separate non-DM code? Another option would be init.h because board_init_r.c:initr_trap() is the only caller. -- - Daniel ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

I think we tend to think of interrupts and exceptions as being similar. Are you suggesting creating a new traps_legacy.h?
