will be copied to another RAM location (Secure World) by SMC

CONFIG_STANDALONE_LOAD_ADDR has been used for examples/standalone
but not for examples/api.
The suitability of an address to load an ELF binary and run it does
not only depend on the architecture but also on the memory layout of
the board which is not reflected in the default value of
CONFIG_STANDALONE_LOAD_ADDR.
Commit 32b7e39db4d3 ("Convert CONFIG_STANDALONE_LOAD_ADDR to Kconfig")
set the default on RISC-V to 0x0 though most boards used 0x80200000
before the patch.
On most boards we can assume 8 MiB of memory available above $loadaddr.
So we can safely use $loadaddr + 4 MiB as load address for the standalone
example and eliminate CONFIG_STANDALONE_LOAD_ADDR altogether.

image: apply FDTOs on FDT image node without a load property
A FIT image which is NOT using -E when created by mkimage - that is with
image data within the FIT - will fail to apply FDTO if the base FDT
image node does not specify a load property (which points to an address
in DRAM). This is because we check that the FDT address we want to apply
overlay to (i.e. modify and likely increase in size) is not inside the
FIT and give up otherwise. This is assumed necessary because we may then
overwrite other data when applying in-place.
However, we can do better than giving up: relocating the FDT in another
place in DRAM where it's safe to increase its size and apply FDTOs.
While at it, do not discriminate anymore on whether the data is within
the FIT data address space - that is FIT images created with mkimage -E
- as that still may be susceptible to unintended data overwrites as
mkimage -E simply concatenates all blobs after the FIT. If the FDT blob
isn't the last, it'll result in overwriting later blobs when resizing.
The side effect is that the load property in the FIT is only
temporarily used to load the FDT but then relocated right before we
start applying overlays.

Merge patch series "mediatek: final preparation for OF_UPSTREAM support"
Christian Marangi <ansuelsmth@gmail.com> says:
This is the last batch of part to push actual support of
OF_UPSTREAM for the mediatek SoC.
The plan is to make the current downstream DTS on part with
upstream implementation so we can permit a gradual transition to
it while we don't cause any regression to any user.
This is to have the same node downstream and upstream.
Mediatek is working hard upstream to also push all the remaining
nodes.
All patch are the final changes after the pinctrl patch
merged previously.
