We provide a UEFI driver for block devices. When ConnectController() is
called for a handle with the EFI_BLOCK_IO_PROTOCOL this driver creates the
partitions. When DisconnectController() is called the handles for the
partitions have to be deleted. This requires that the child controllers
(partitions) open the EFI_BLOCK_IO_PROTOCOL of the controller (block IO
device) with attribute EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.

At present this function returns 1 on success and 0 on failure. But in

A capsule tagged with the guid, EFI_FIRMWARE_MANAGEMENT_CAPSULE_ID_GUID,
is handled as a firmware update object.
What efi_update_capsule() basically does is to load any firmware management
protocol (or fmp) drivers contained in a capsule, find out an appropriate
fmp driver and then invoke its set_image() interface against each binary

In this commit, however, loading drivers is not supported.

Capsule data can be loaded into the system either via UpdateCapsule

The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.
In this commit, we will support capsule on disk mechanism.
Please note that U-Boot itself has no notion of "boot device" and

are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

Also if the tables point to other tables (such as console log or a ramoops

Pull request for UEFI sub-system for efi-2021-01-rc2 (2)
The series contains the following enhancements
* preparatory patches for UEFI capsule updates
* initialization of the emulated RTC using an environment variable
and a bug fix
* If DisconnectController() is called for a child controller that is the
only child of the driver, the driver must be disconnected.
Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.
This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.
The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?
I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.
