f89b90d2d9 configs: add khadas-vim3{l}_android for AOSP support
The Khadas VIM3 and VIM3L board are well supported in AOSP[1].
However, there is no mainline U-Boot support for it.
The U-Boot used in AOSP is based on a vendor tree [2]

Add all the necessary bits to flash and boot Android for both Khadas
VIM3 and VIM3L boards.

For Android instructions, refer to [1]

ede1f4f297 configs: amlogic: Disable CONFIG_NET_RANDOM_ETHADDR when unnecessary
On Meson GXL, GXM, AXG, G12A, G12B & SM1 SoCs, we can generate an unique
MAC address if none valid found in the eFuses storage.

Only the GXBB based boards doesn't have a fallback way to generate an
unique MAC address, so we rely on CONFIG_NET_RANDOM_ETHADDR to have
a valid one.

An exception is the Radxa Zero board who doesn't have Ethernet on board
so depends on an (or multiple) eventual USB adapters, so leaving the
CONFIG_NET_RANDOM_ETHADDR configs seems safer.

b5ffc9f758 net: zynq: Add support for GEM reset
Perform reset before core initialization.
Standard flow which close to 99% users are using getting all IPs out of
reset that there is no need to reset IP again. This is because of all low
level initialization is done in previous bootloader stage.
In SOM case these IPs are not touched by previous bootloader stage that's
why reset needs to be called before IP is accessed to make sure that it is
in correct state.

12133b11a7 net: zynq: Add support for mdio bus address decoding
Xilinx DTS files are using two way how to describe ethernet phy.

The first (already supported) has phy as subnode of gem node.
eth {
        phy-handle = <&phy0>;
         phy0: ethernet-phy@21 {
                ...
        };
};

The second has mdio subnode (with mdio name) which has phy subnode. This
structure allow hadling MDIO reset signal (based on Linux mdio.yaml)
eth {
        phy-handle = <&phy0>;
        mdio {
                phy0: ethernet-phy@21 {
                        ...
                };
        };
};

This patch adds support for the second case where mdio subnode
is found driver will look at its parent to find out which gem is handling
MDIO bus.

86bb48880d x86: efi: Don't set up global_data again with EFI
Since EFI does not relocate and uses the same global_data pointer
throughout the board-init process, drop this unnecessary setup, to avoid
a hang.

40b172314b x86: efi: Show the system-table revision
Show the revision of this table as it can be important.

Also update the 'efi table' entry to show the actual address of the EFI
table rather than our table that points to it. This saves a step and the
intermediate table has nothing else in it.

cf376037e2 efi: Mention that efi_info_get() is only used in the stub
This provides access to EFI tables after U-Boot has exited boot services.
It is not needed in the app since boot services remain alive and we can
just call them whenever needed.

Add a comment to explain this.

bc53a35ac5 efi: Check for failure when initing the app
The stub checks for failure with efi_init(). Add this for the app as well.
It is unlikely that anything can be done, but we may as well stop.
