645502743a eficonfig: avoid SetVariable between GetNextVariableName calls
The current code calls efi_set_variable_int() to delete the
invalid boot option between calls to efi_get_next_variable_name_int(),
it may produce unpredictable results.

This commit moves removal of the invalid boot option outside
of the efi_get_next_variable_name_int() calls.
EFI_NOT_FOUND returned from efi_get_next_variable_name_int()
indicates we retrieved all EFI variables, it should be treated
as EFI_SUCEESS.

To address the checkpatch warning of too many leading tabs,
combine two if statement into one.

ce3270849b eficonfig: carve out efi_get_next_variable_name_int calls
To retrieve the EFI variable name by efi_get_next_variable_name_int(),
the sequence of alloc -> efi_get_next_variable_name_int ->
realloc -> efi_get_next_variable_name_int is required.
In current code, this sequence repeatedly appears in
the several functions. It should be curved out a common function.

This commit also fixes the missing free() of var_name16
in eficonfig_delete_invalid_boot_option().

140a8959d4 eficonfig: use efi_get_next_variable_name_int()
eficonfig command reads all possible UEFI load options
from 0x0000 to 0xFFFF to construct the menu. This takes too much
time in some environment.
This commit uses efi_get_next_variable_name_int() to read all
existing UEFI load options to significantlly reduce the count of
efi_get_var() call.

c3b5af63d1 eficonfig: add UEFI Secure Boot Key enrollment interface
This commit adds the menu-driven UEFI Secure Boot Key
enrollment interface. User can enroll PK, KEK, db
and dbx by selecting file.
Only the signed EFI Signature List(s) with an authenticated
header, typically '.auth' file, is accepted.

To clear the PK, KEK, db and dbx, user needs to enroll the null key
signed by PK or KEK.

d571f9b23e eficonfig: refactor change boot order implementation
All the eficonfig menus other than "Change Boot Order"
use 'eficonfig_entry' structure for each menu entry.
This commit refactors change boot order implementation
to use 'eficonfig_entry' structure same as other menus
to have consistent menu handling.

This commit also simplifies the data->active handling when
KEY_SPACE is pressed, and sizeof() parameter.

a84040ab46 eficonfig: refactor file selection handling
eficonfig_select_file_handler() is commonly used to select the
file. eficonfig_display_select_file_option() adds an additional
menu to clear the selected file.
eficonfig_display_select_file_option() is not always necessary
for the file selection process, so it must be outside of
eficonfig_select_file_handler().

This commit also renames the following functions to avoid confusion.
 eficonfig_select_file_handler() -> eficonfig_process_select_file()
 eficonfig_select_file() -> eficonfig_show_file_selection()
 eficonfig_display_select_file_option() -> eficonfig_process_show_file_option()

Finally, test_eficonfig.py need to be updated to get aligned with
the above modification.

This commit adds the menu entry to update UEFI BootOrder variable.
User moves the entry with UP/DOWN key, changes the order
with PLUS/MINUS key, press SPACE to activate or deactivate
the entry, then finalizes the order by ENTER key.
If the entry is activated, the boot index is added into the
BootOrder variable in the order of the list.

The U-Boot menu framework is well designed for static menu,
this commit implements the own menu display and key handling
for dynamically change the order of menu entry.

c416f1c0bc bootmenu: add removable media entries
UEFI specification requires booting from removal media using
a architecture-specific default image name such as BOOTAA64.EFI.
This commit adds the removable media entries into bootmenu,
so that user can select the removable media and boot with
default image.

The bootmenu automatically enumerates the possible bootable
media devices supporting EFI_SIMPLE_FILE_SYSTEM_PROTOCOL,
add it as new UEFI boot option(BOOT####) and update BootOrder
variable. This automatically generated UEFI boot option
has the dedicated guid in the optional_data to distinguish it from
the UEFI boot option user adds manually. This optional_data is
removed when the efi bootmgr loads the selected UEFI boot option.

This commit also provides the BOOT#### variable maintenance feature.
Depending on the system hardware setup, some devices
may not exist at a later system boot, so bootmenu checks the
available device in each bootmenu invocation and automatically
removes the BOOT#### variable corrensponding to the non-existent
media device.
