[PATCH 0/2] EFI/menu: Do not print messages when autobooting with TIMEOUT_STYLE_HIDDEN

[Hans de Goede]

Hi All,

This series in essence is a renewed attempt to get grub to really
be truly hidden when autobooting with TIMEOUT_STYLE_HIDDEN.

This is something which multiple big Linux distributions want,
this is a minimized version of my previous attempt from March 2018:
https://lists.gnu.org/archive/html/grub-devel/2018-03/msg00126.html
With some discussion about this patch in April 2018:
https://lists.gnu.org/archive/html/grub-devel/2018-04/msg00009.html

The first patch silences the notify_booting() callback from
grub-core/normal/menu.c based on the timeout_style (1), as
suggested in the original discussion.

After that there is just one message left, from grub-core/kern/main.c
which is printed before the config file loads. When timeout_style
is not set to hidden this will only show very briefly to then be
replaced by the menu / countdown; and with timeout_style=hidden
we actually want it to behave the same as any other grub messages
and have it hidden. The second patch makes this happen by just
disabling the logging of the message for EFI builds.

This also fixes the message briefly flashing by (in an ugly manner
because of the "flash" part) when timeout_style!=hidden.

Regards,

Hans
