This is probably something of a foot-gun but here we go...
I was wondering if it's worth providing the ability to silence the output from the SPL. CONFIG_SILENT_CONSOLE exist for u-boot proper but the SPL preloader_console_init bypasses anything that would set GD_FLG_SILENT. Even if it didn't the SPL probably doesn't have access to any environment that would allow it to be set/unset.
I was thinking about adding a SPL specific CONFIG option that would set GD_FLG_SILENT (probably in spl_init). Aside from re-compiling there wouldn't be any way of making the SPL loud. Is this a reasonable idea or is it just asking for boards to be bricked with no way of telling what went wrong?
I have a at91 based board in mainline, which has no SPL output enabled (as there is no space for it), see:
configs/smartweb_defconfig
Do not define CONFIG_SPL_SERIAL_SUPPORT=y
