This is a preparation patch to provide the unified method
to access udevice pointer associated with the EFI handle
by adding udevice pointer into struct efi_object.
The patch also introduces a helper function efi_link_dev()
to link the udevice and EFI handle.
The EFI handles of both EFI block io driver implemented in
lib/efi_loader/efi_disk.c and EFI block io driver implemented
as EFI payload can access the udevice pointer in the struct efi_object.
We can use this udevice pointer to get the U-Boot friendly
block device name(e.g. mmc 0:1, nvme 0:1) through EFI handle.

Changes in v10:
- introduce efi_link_dev() and remove accessor macro
- set udevice in efi_bl_bind()

This commit add the "eficonfig" command.
The "eficonfig" command implements the menu-driven UEFI boot option
maintenance feature. This commit implements the addition of
new boot option. User can select the block device volume having
efi_simple_file_system_protocol and select the file corresponding
to the Boot#### variable. User can also enter the description and
optional_data of the BOOT#### variable in utf8.
This commit adds "include/efi_config.h", it contains the common
definition to be used from other menus such as UEFI Secure Boot
key management.

Changes in v10:
- add initrd file selection
- do refactoring
- eficonfig_process_common() use list structure
- remove u'/' before copying file_path into current_path
- fix typos
- check snprintf error
Changes in v9:
- move "efi_guid_bootmenu_auto_generated definition" into efi_bootmgr.c
to address build error when CMD_EFICONFIG is disabled
- fix typos and comment
- remove file system information from error message
- remove unreachable code in eficonfig_choice_entry()
- single printf() call as much as possible
- call only getchar() in eficonfig_print_msg()
- filter out '.' entry from file selection
- update the efi_disk_get_device_name() implementation
- add function comment
Changes in v8:
- command name is change from "efimenu" to "eficonfig"
- function and struct prefixes is changed to "eficonfig"
- fix menu header string
Changes in v7:
- add "efimenu" command and uefi variable maintenance code
moved into cmd/efimenu.c
- create include/efimenu.h to define the common definition for
the other menu such as UEFI Secure Boot key management
- update boot option edit UI, user can select description, file,
and optional_data to edit in the same menu like following.
** Edit Boot Option **
Description: debian
File: virtio 0:1/EFI\debian\grubaa64.efi
Optional Data: test
Save
Quit
- remove exit parameter from efimenu_process_common()
- menu title type is changed from u16 to char
- efimenu_process_common() add menu title string
- reduce printf/puts function call for displaying the menu
- efi_console_get_u16_string() accept 0 length to allow
optional_data is empty
- efi_console_get_u16_string() the "size" parameter name is changes to "count"
- efimenu is now designed to maintain the UEFI variables, remove autoboot related code
- remove one empty line before "Quit" entry
- efimenu_init() processes only the first time
Changes in v6:
- fix typos
- modify volume name to match U-Boot syntax
- compile in CONFIG_EFI_LOADER=n and CONFIG_CMD_BOOTEFI_BOOTMGR=n
- simplify u16_strncmp() usage
- support "a\b.efi" file path, use link list to handle filepath
- modify length check condition
- UEFI related menu items only appears with CONFIG_AUTOBOOT_MENU_SHOW=y
Changes in v5:
- remove forward declarations
- add const qualifier for menu items
- fix the possible unaligned access for directory info access
- split into three commit 1)add boot option 2) delete boot option 3)change boot order
This commit is 1)add boot option.
- fix file name buffer allocation size, it should be EFI_BOOTMENU_FILE_PATH_MAX * sizeof(u16)
- fix wrong size checking for file selection
Chanes in v4:
- UEFI boot option maintenance menu is integrated into bootmenu
- display the simplified volume name(e.g. usb0:1, nvme1:2) for the
volume selection
- instead of extending lib/efi_loader/efi_bootmgr.c, newly create
lib/efi_loader/efi_bootmenu_maintenance.c and implement boot
variable maintenance into it.
Changes in RFC v3:
not included in v3 series
Changes in RFC v2:
- enable utf8 user input for boot option name
- create lib/efi_loader/efi_console.c::efi_console_get_u16_string() for
utf8 user input handling
- use u16_strlcat instead of u16_strcat
- remove the EFI_CALLs, and newly create or expose the following
xxx_int() functions.
efi_locate_handle_buffer_int(), efi_open_volume_int(),
efi_file_open_int(), efi_file_close_int(), efi_file_read_int() and
efi_file_setpos_int().
Note that EFI_CALLs still exist for EFI_DEVICE_PATH_TO_TEXT_PROTOCOL
and EFI_SIMPLE_TEXT_INPUT/OUTPUT_PROTOCOL
- use efi_search_protocol() instead of calling locate_protocol() to get
the device_path_to_text_protocol interface.
- remove unnecessary puts(ANSI_CLEAR_LINE), this patch is still depends on
puts(ANSI_CLEAR_CONSOLE)
- skip SetVariable() if the bootorder is not changed

This commit adds the menu entry to edit the existing
BOOT#### variable contents.
User selects the item from the boot option list, then
user can edit the description, file path and optional_data.
Note that automatically generated boot option entry by bootmenu
to support the removable media device is filtered out and user
can not edit the automatically generated entry.

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, then finalizes the order by ENTER key.
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.

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.

Changes in v10:
- add function comment
- devname dynamic allocation removes, allocate in stack
- delete BOOT#### when updating BootOrder fails
Changes in v9:
- update efi_disk_get_device_name() parameter to pass efi_handle_t
- add function comment
Changes in v8:
- function and structure prefix is changed to "eficonfig"
Changes in v7:
- rename prepare_media_device_entry() to generate_media_device_boot_option()
Changes in v6:
- optional_data size is changed to 16bytes
- check the load option size before comparison
- remove guid included in optional_data of auto generated
entry when loading
Changes in v5:
- Return EFI_SUCCESS if there is no BootOrder defined
- correctly handle the case if no removable device found
- use guid to identify the automatically generated entry by bootmenu

The bootmenu enumerates the UEFI boot options
for boot device selection.
This commit adds the description how the UEFI boot work
in bootmenu. This commit also adds "Synopsis", "Description"
and "Configuration" sections to follow the U-Boot command
documentation format.

+eficonfig command
+=================
+
+Synopsis
+--------
+::
+
+ eficonfig
+
+Description
+-----------
+
+The "eficonfig" command uses U-Boot menu interface and privides
+a menu-driven UEFI variable maintenance feature.
+The "eficonfig" has the following menu entries.
+
+Add Boot Option
+ Add new UEFI Boot Option.
+ User can edit description, file path, and optional_data.
+
+Edit Boot Option
+ Edit the existing UEFI Boot Option
+ User can edit description, file path, and optional_data.
+
+Change Boot Order
+ Change the order of UEFI BootOrder variable.
+
+Delete Boot Option
+ Delete the UEFI Boot Option
+
+Configuration
+-------------
+
+The "eficonfig" command is enabled by::
+
+ CONFIG_CMD_EFICONFIG=y
+
+If CONFIG_BOOTMENU_DISABLE_UBOOT_CONSOLE is enabled, user can not enter
+U-Boot console. In this case, bootmenu can be used to invoke "eficonfig"::
+
+ CONFIG_USE_PREBOOT=y
+ CONFIG_PREBOOT="setenv bootmenu_0 UEFI Maintenance Menu=eficonfig"
+
+How to boot the system with newly added UEFI Boot Option
+''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+"eficonfig" command is responsible to configure the UEFI variables,
+not directly handle the system boot.
+The new Boot Option added by "eficonfig" is appended at the last entry
+of UEFI BootOrder variable, user may want to change the boot order
+through "Change Boot Order".
+If the bootmenu is enabled and "eficonfig" is configured as preboot command,
+the newly added Boot Options are enumerated in the bootmenu when user exits
+from the eficonfig menu.
+User may select the entry in the bootmenu to boot the system, or follow
+the U-Boot configuration the system already has.

I tried to load an initrd, which on typical distros is not part of the
ESP. While
=> ls virtio 0:2
reads the filesystem contents fine, whenI try to navigate to that
virtio (and ext4 filesystem) device through the menu I am getting:
"Reading volume failed!"
Any ideas?

eficonfig_select_file()
efi_file_open_int()
file_open()
exists = fs_exists(fh->path);
...
It seems that fat and ext4 work in a different way against a *directory* here.
For instance, try this both on fat and ext4
("test -e" internally uses fs_exists().)
=> test -e virtio X:Y /
=> echo $?
I think eficonfig_select_file() can be rewritten with fs_opendir()/fs_readdir().
(Or much more preferably, efi_open(), and essentially fs_exists(), should be fixed.)

Correction:
Not all file systems support fs_opendir/fs_readdir interfaces, so this is not
a viable solution in general.
(Please note that UEFI spec says nothing about file systems other than fat, though.)

I have defined multiple boot options. But the efidebug command does not
allow to edit them. I just get an error message
BootOrder is not defined!
When BootOrder is defined I can only edit the BootOptions defined by
boot order.
Editing boot options *must not* depend on variable BootOrder. The only
BootOptions that shall not be editable are the autogenerated ones media.

If BootOrder is not defined efidebug does no allow to edit the boot
order. It just shows an error message
BootOrder is not defined!
If BootOrder is defined I can only change the sequence but neither add
not delete an entry.
eficonfig must allow:
* add any boot option to the sequence including autogenerated ones
* delete any boot option from the sequence including autogenerated ones
Best regards

lib/efi_loader/efi_file.c calls fs_opendir()/fs_readdir() to access
the directory information,
and ext4 file system code does not support fs_opendir()/fs_readdir().
I could not find any generic method to read directory information for
the file system
that U-Boot supports. It seems that it requires much effort to support
creating the
file selection menu other than FAT file system.

In the next version, I implement to toggle activate/deactivate the
entry by SPACE key as follows.
** Change Boot Order **
[*] virtio 0:2
[ ] virtio 0:1
[*] debian
[ ] ubuntu
Save
Quit
Press UP/DOWN to move, +/- to change order
Press SPACE to activate or deactivate the entry
Select [Save] to complete, ESC/CTRL+C to quit
