For handling added and removed block devices we need to register events
which has to be done when the driver is installed.
This patch only creates an empty init function that will be filled with

are used. Move the efi_driver_init() call to early init.

This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.
It is only for SPL that we have two cases:
- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
use blk_legacy.c
Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.

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.

Change efi_delete_handle() to not free EFI handles twice.
This change tries to resolved an issue seen since U-Boot v2022.07
in which ExitBootService() attempts to release some EFI handles twice.
The issue was seen booting a EFI shell that invokes 'connect -r' and
then boots a Linux kernel. Execution of connect command makes EFI
subsystem to bind a block device for each root block devices EFI handles.
However these EFI device handles are already bound to a driver and we
can have 2 registered devices relating to the same EFI handler. On
ExitBootService(), the loop removing the devices makes these EFI handles
to be released twice which corrupts memory.
This patch prevents the memory release operation caused by the issue but
but does not resolve the underlying problem.

The requsted partition disk sector incorrectly has the parition start
sector added in twice for UCLASS_PARTITION devices. The efi_disk_rw_blocks()
routine adds the diskobj->offset to the requested lba. When the device
is a UCLASS_PARTITION, the dev_read() or dev_write() routine is called
which adds part-gpt_part_info.start. This causes I/O to the wrong sector.
Takahiro Akashi suggested removing the offset field from the efi_disk_obj
structure since disk-uclass.c handles the partition start biasing. Device
types other than UCLASS_PARTITION set the diskobj->offset field to zero
which makes the field unnecessary. This change removes the offset field
from the structure and removes all references from the code which is
isolated to the lib/efi_loader/efi_disk.c module.
This change also adds a test for the EFI ReadBlocks() API in the EFI
selftest code. There is already a test for reading a FAT file. The new
test uses ReadBlocks() to read the same "disk" block and compare it to
the data read from the file system API.

Under the current implementation, booting from removable media using
a architecture-specific default image name, say BOOTAA64.EFI, is
supported only in distro_bootcmd script. See the commit 74522c898b
("efi_loader: Add distro boot script for removable media").
This is, however, half-baked implementation because
1) UEFI specification requires this feature to be implemented as part
of Boot Manager's responsibility:
3 - Boot Manager
3.5.1 Boot via the Simple File Protocol
When booting via the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, the FilePath will
start with a device path that points to the device that implements the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or the EFI_BLOCK_IO_PROTOCOL. The next
part of the FilePath may point to the file name, including
subdirectories, which contain the bootable image. If the file name is
a null device path, the file name must be generated from the rules
defined below.
...
3.5.1.1 Removable Media Boot Behavior
To generate a file name when none is present in the FilePath, the
firmware must append a default file name in the form
\EFI\BOOT\BOOT{machine type short-name}.EFI ...
2) So (1) entails the hehavior that the user's preference of boot media
order should be determined by Boot#### and BootOrder variables.
With this patch, the semantics mentioned above is fully implemented.
For example, if you want to boot the system from USB and SCSI in this
order,
* define Boot0001 which contains only a device path to the USB device
(without any file path/name)
* define Boot0002 which contains only a device path to the SCSI device,
and
* set BootOrder to Boot0001:Boot0002
To avoid build error for sandbox, default file name "BOOTSANDBOX.efi"
is defined even if it is out of scope of UEFI specification.
