Subject: [PATCH] efi/linux: provide linux command
|
|
|
|
The linux kernel's efi handover entry point is used to boot efistub of
|
|
the linux kernel. Since then the efistub has been improved with many new
|
|
features and fixes that ordinary 32-bit entry point cannot provide.
|
|
|
|
Besides, nearly every x86 efi kernel is built with efistub enabled so it
|
|
is of little value to keep 32-bit entry as default to boot kernel
|
|
without needed kconfig options enabled.
|
|
|
|
For all good reasons, making efi handover the default entry point for
|
|
booting kernel in x86 efi platform so that linux command works in the
|
|
same way to linuxefi. This can also reduce the complexity of providing
|
|
general grub configuation for x86 system due to the linux command may
|
|
not be available in signed image for UEFI Secure Boot and linuxefi is
|
|
not available for leagcy bios booting.
