So if actually you want a pre-console panic() to be silent then that's fine. It's a little unfriendly though - so would you be interested in keeping board_pre_console_putc() around if we could solve this entirely with code in there? It turns out that Tegra has a setting for console UART in the hardware parameters that we can access.( I won't ask you about how to handle a panic() in SPL yet).
