fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().
UEFI on ARM requires that unaligned memory access is enabled.
* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
For none of the other cpus in arch/arm/cpu/ we have implemented a
similar function.
* ARMv8 allows unaligned access.
Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.
Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.

The loading convention for optee or any other tee on arm64 is as bl32
parameter to the trusted-firmware. So TF-A gets invoked with the TEE as
bl32 and main u-boot as bl33. Once it has done its startup TF-A jumps
into the bl32 for the TEE startup, returns to TF-A and then jumps to bl33.
All of them get passed a devicetree as parameter and all components often
get loaded from a FIT image.
OP-TEE will create additional nodes in that devicetree namely a firmware
node and possibly multiple reserved-memory nodes.
While this devicetree is used in main u-boot, in most cases it won't be
the one passed to the actual kernel. Instead most boot commands will load
a new devicetree from somewhere like mass storage of the network, so if
that happens u-boot should transfer the optee nodes to that new devicetree.
To make that happen introduce optee_copy_fdt_nodes() called from the dt
setup function in image-fdt which after checking for the optee presence
in the u-boot dt will make sure a optee node is present in the kernel dt
and transfer any reserved-memory regions it can find.

The phandlep pointer returning the phandle to the caller is optional
and if it is not set when calling fdtdec_add_reserved_memory() it is
highly likely that the caller is not interested in a phandle to the
created reserved-memory area and really just wants that area added.
So just don't create a phandle in that case.

The change adding fdtdec_add_reserved_memory() already protected the added
phandle against the phandlep being NULL - making the phandlep var optional.
But in the early code checking for an already existing carveout this check
was not done and thus the phandle assignment could run into trouble,
so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to
work with the phandle.
