b6e9e09770 efi_loader: initialise partition_signature memory
Zero partition_signature in the efi_device_path_hard_drive_path
structure when signature_type is 0 (no signature) as required by the
UEFI specification.

This is required so that efi_dp_match() will work as expected
when doing memcmp() comparisons.  Previously uninitialised memory
would cause it not match nodes when it should have when the signature
type was not GUID.

Corrects a problem where the loaded image protocol would not return a
device path with MEDIA_DEVICE causing the OpenBSD bootloader to fail
on rpi_3 and other targets.

v2: Also handle signature_type 1 (MBR) as described in the specification

ebb4dd5bc3 efi_loader: efi_console: use helper functions
Use helper functions efi_created_handle and efi_add_protocol
for creating the console handles and instaling the respective
protocols.

This change is needed if we want to move from an array of
protocols to a linked list of protocols.

Eliminate EFI_PROTOCOL_OBJECT which is not used anymore.

Currently we have not defined protocol interfaces to be const.
So efi_con_out and efi_console_control cannot be defined as const.

d78e40d651 efi_selftest: allow to select a single test for execution
Environment variable efi_selftest is passed as load options
to the selftest application. It is used to select a single
test to be executed.

The load options are an UTF8 string. Yet I decided to keep
the name propertiy of the tests as char[] to reduce code
size.

Special value 'list' displays a list of all available tests.

Tests get an on_request property. If this property is set
the tests are only executed if explicitly requested.

The invocation of efi_selftest is changed to reflect that
bootefi selftest with efi_selftest = 'list' will call the
Exit bootservice.

5f104178bf rockchip: dts: rk3399-puma: add /config/sysreset-gpio property
On the RK3399-Q7, we want to trigger a full platform reset (so the
various software stacks supported don't have to deal with the same
complexities over and over again) in case that anything other than a
power-on reset occurred.

To do so, this defines the /config/sysreset-gpio property and has it
point to a GPIO that will perform a power-on reset of the entire
platform.

ae0d33a729 rockchip: rk3399-puma: add code to allow forcing a power-on reset
The reset circuitry in the RK3399 only resets 'almost all logic' when
a software reset is performed.  To make our software maintenance
easier in the future, we want to have the option (controlled by a DTS
property) to force all reset causes other than a power-on reset to
trigger a power-on reset via a GPIO trigger.

This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7)
board-support and the documentation for the new property
(sysreset-gpio) within the /config-node.

884ad05d34 rockchip: dts: rk3399-puma: add a 'tsd, usb-port-power' stringlist for USB1
USB1 is connected to the on-module USB 3.0 hub and power to the hub
(actually it's a reset signal, modeled as a fixed regulator, that will
be released) should be enabled only during the first probing of the
device to avoid the hub from entering its low-power mode (where it
tries to attach on a fixed interval, but we always miss the timeslot
when U-Boot has the controller listening).

This adds a 'tsd,usb-port-power' stringlist to enable the
infrastructure in the board-specific usb_hub_reset_devices to find and
control the fixed regulator associated with control of the USB hub.
