[PATCH v2 1/3] eficonfig: refactor eficonfig_process_common function
Masahisa Kojima

Fri Dec 23 23:57:42 CET 2022
Current change boot order implementation does not call
eficonfig_process_common() and call own menu functions
for display_statusline, item_data_print and item_choice.
Change boot order functionality should call
eficonfig_process_common() to improve maintenanceability.
This commit is a preparation to remove the change boot
order specific implementation. The menu functions
(display_statusline, item_data_print and item_choice) are
added as argument of eficonfig_process_common().
The menu description string displayed at the bottom of
the menu is also added as argument.

Changes in v2:
- add const qualifier to eficonfig_menu_desc, change it to pointer
