e472ef8a3d efi_loader: fix device-path for USB devices
EFI device paths for block devices must be unique. If a non-unique device
path is discovered, probing of the block device fails.

Currently we use UsbClass() device path nodes. As multiple devices may
have the same vendor and product id these are non-unique. Instead we
should use Usb() device path nodes. They include the USB port on the
parent hub. Hence they are unique.

A USB storage device may contain multiple logical units. These can be
modeled as Ctrl() nodes.

26a35023c4 efi_loader: update SetVariable attribute check
UEFI specification v2.10 says that
EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS is deprecated and
EFI_UNSUPPORTED should be returned in SetVariable variable service.
Current implementation returns EFI_INVALID_PARAMETER,
let's fix the return value.

Together with above change, this commit also updates the SetVariable
attribute check to be aligned with the EDK2 reference implementation.

454a9442fb efi_loader: update attribute check for QueryVariableInfo()
Current U-Boot supports two EFI variable service, U-Boot own
implementation and op-tee based StMM variable service.

With ACS Security Interface Extension(SIE) v22.10_SIE_REL1.1.0,
there are several failure items of QueryVariableInfo().

Current attribute check for QueryVariableInfo() was implemented
based on the Self Certification Test (SCT) II Case Specification,
June 2017, chapter 4.1.4 QueryVariableInfo().
This test case specification is outdated and don't align at all
with the SCT test case code, and UEFI specification v2.10 does
not clearly define the priority of the attribute check.

For U-Boot standard case that EFI variables are stored in a file
in the ESP, this commit modifies the attribute check to get align
to the EDK2 implementation.

For latter case(op-tee based StMM variable service), parameter check
should be delegated to StMM.

Now all ACS SIE QueryVariableInfo() test cases passed both EFI variable
storage implementations.

448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

60bba6e205 efi_loader: populate console handles in system table
The fields ConsoleInHandle, ConsoleOutHandle, ConsoleErrHandle must point
to the handles with the respective console protocols. Failure to do so
leads to an error in the EFI Shell:

    No SimpleTextInputEx was found. CTRL-based features are not usable.

77bb14758d efi_loader: avoid adding variables twice
When the efi subsystem starts we restore variables that are both in a
file or stored into the .efi_runtime section of U-Boot.  However once
a variable gets created or changed the preseeded entries will end up in
the file.  As a consequence on the next boot we will end up adding
identical variable entries twice.

Fix this by checking if the to be inserted variable already exists.
Also swap the restoration order and start with the file instead of the
builtin variables,  so a user can replace the preseeded ones if needed.

c33d389c7a efi_loader: fix get_package_list_handle() status
When the HII protocol function get_package_list_handle() is called with an
invalid package list handle, it returns EFI_NOT_FOUND but this is not in
its list of possible status codes as per the EFI specification.
Return EFI_INVALID_PARAMETER instead to fix conformance.
