[PATCH v5 0/4] eficonfig: add vertical scroll support and refactoring

[Masahisa Kojima]

This series aims to add the vertical scroll for the eficonfig menu.
Before adding scroll support, this series does the refactoring
of change boot order implementation since it has own menu handling
and it should be removed to improve maintainability.

The eficonfig menu handles file selection for EFI load option
and secure boot keys, it likely to enumerate tens of files.
User can not select the file without scroll if theare are
many files under the target directory.

This series only modifies the eficonfig menus. Other menus
such as bootmenu is not yet done. We need to enhance the
U-Boot menu framework itself if we support other menus.

Masahisa Kojima (4):
  eficonfig: refactor eficonfig_process_common function
  eficonfig: refactor change boot order implementation
  eficonfig: add vertical scroll support
  eficonfig: increase the number of menu entries

[PATCH v5 1/4] eficonfig: refactor eficonfig_process_common function

[Masahisa Kojima]

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.

[PATCH v5 2/4] eficonfig: refactor change boot order implementation

[Masahisa Kojima]

This commit removes the change boot order specific
menu implementation. The change boot order implementation
calls eficonfig_process_common() same as other menus.

The change boot order menu requires own item_data_print
and item_choice implementation, but display_statusline
function can be a same function as other menus.

[PATCH v5 3/4] eficonfig: add vertical scroll support

[Masahisa Kojima]

The current eficonfig menu does not support vertical scroll,
so it can not display the menu entries greater than
the console row size.

This commit add the vertial scroll support.
The console size is retrieved by
SIMPLE_TEXT_OUTPUT_PROTOCOL.QueryMode() service, then
calculates the row size for menu entry by subtracting
menu header and description row size from the console row size.
"start" and "end" are added in the efimenu structure.
"start" keeps the menu entry index at the top, "end" keeps
the bottom menu entry index. item_data_print() menu function
only draws the menu entry between "start" and "end".

This commit also fixes the issue that "Save" and "Quit"
entries can be moved by BKEY_PLUS in change boot order menu.

Changes in v5:
- create common function to update efi_menu active, start and end
- fix the issue that "Save" and "Quit" can be moved by BKEY_PLUS press

Changes in v3:
- modify "reverse" local variable type to bool

Changes in v2:
- add comment when the user key press is not valid
- add const qualifier to eficonfig_change_boot_order_desc

[PATCH v5 4/4] eficonfig: increase the number of menu entries

[Masahisa Kojima]

Current eficonfig has the maximum number of menu entries and
it is 99. If there are more EFI load options and files in the
system, eficonfig can not handle it.

This commit increases this maximum number of menu entries
to INT_MAX.

Hello Masahisa,

my example with 100 boot options works fine now. I will get that series
merged.

When I edit the boot order and want to save the changes I have to scroll
down up to INT_MAX lines to reach the line with "Save". Can't we just
use CTRL+S for saving in a future patch?

"ESC/CTRL+C to quit" is misleading:
On the sandbox called without "--terminal raw" CTRL+C leaves U-Boot. How
about removing "/CTRL+C" from that text?

Best regards

Heinrich

OK, I will send patches for both comments.
