AllocatePages() can be called with Type=AllocateAddress. Such a call can
only succeed if *Memory points to the address of an unallocated page range.

A call with *Memory being an address that is not page aligned must not
succeed. The UEFI specification requires returning EFI_OUT_OF_RESOURCES
if the requested pages cannot be allocated.

Variable efi_system_partition holds the efi_system_partition. Currently it
is initialized as:

    {
      .uclass_id = 0 = UCLASS_ROOT,
      .denum = 0,
      .part = 0,
    }

This indicates that host 0:0 is the efi_system_partition and we see output
like:

    => bootefi hello
    ** Bad device specification host 0 **
    Couldn't find partition host 0:0

To identify that no EFI system partition has been set use UCLASS_INVALID.

Since the commit a9bf024b2933 ("efi_loader: disk: a helper function to
create efi_disk objects from udevice"), CONFIG_EFI_SETUP_EARLY option is
by default on and will never be turned off.

So just remove this option.

CONFIG_NET does not imply that there are actually network devices
available, only CONFIG_NETDEVICES does. Changing to this dependency
obsoletes the check in Kconfig because NETDEVICES means DM_ETH.

The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.

At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

Use the uclass type as the first part of the function name, to be
consistent with the methods in other block drivers.

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Rename it to resolve this problem.

This relies on the old LCD implementation which is to be removed. Drop the
existing #ifdef and convert it to C code.

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.

Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.

Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.

Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.
